Common CAS Numbers

Chemical Formulas

A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs. For example, the chemical formula for Nitric Acid is HNO3. A CAS Registry Number, also referred to as CASRN or CAS Number, is a unique numerical identifier assigned by the Chemical Abstracts Service (CAS) to every chemical substance described in the open scientific literature (currently including all substances described from 1957 through the present, plus some substances from the early or mid 1900s), including organic and inorganic compounds, minerals, isotopes, alloys and nonstructurable materials (UVCBs, substances of unknown or variable composition, complex reaction products, or biological origin).

The registry maintained by CAS is an authoritative collection of disclosed chemical substance information. It currently identifies more than 144 million unique organic and inorganic substances and 67 million protein and DNA sequences, plus additional information about each substance. It is updated with around 15,000 additional new substances daily.

Where Can I Find A CAS Number?

The CAS Registry Number is the universally recognized unique identifier of chemical substances and is often found on packaging and on articles of commerce. To find a CAS Number, click here.

Common Chemistry™ from Chemical Abstracts Service (CAS), a web resource that contains CAS Registry Numbers for approximately 7,900 chemicals of widespread general public interest. Common Chemistry is helpful to non-chemists who know either a name or CAS Registry Number® of a common chemical and want to pair both pieces of information. The CAS Registry Number is the universally recognized unique identifier of chemical substances and is often found on packaging and on articles of commerce. While not a comprehensive CAS Registry Number lookup service, Common Chemistry does provide a way to quickly and easily find names or CAS Registry Numbers for chemicals of general interest.  CAS has collaborated with Wikipedia in developing this resource and encourages you to use the Wikipedia link (when available) or other sources of general information on chemistry, to learn more about these chemicals.

Do Mixtures Have A CAS Number?

Although a single CAS RN (Registry Number) is not normally assigned to an intentional mixture, CAS RNs are provided for the individual components of the mixture. CAS will assign a single CAS RN to a substance regardless of varying physical forms, except for naturally occurring minerals. For example, water, ice, and water vapor are all represented by CAS RN 7732-18-5. CAS will register specific alloys, ions, isotopes, and elementary particles.

Information On Chemical Substances From Wikipedia

A chemical substance is a form of matter having constant chemical composition and characteristic properties. Chemical substances can be simple substances, chemical compounds, or alloys. Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride) and refined sugar (sucrose). However, in practice, no substance is entirely pure, and chemical purity is specified according to the intended use of the chemical. Chemical substances exist as solids, liquids, gases, or plasma, and may change between these phases of matter with changes in temperature or pressure. Chemical substances may be combined or converted to others by means of chemical reactions. Forms of energy, such as light and heat, are not matter, and are thus not "substances" in this regard.

April 8, 2020

For pesticide registration information, review this list from the EPA, "List G: EPA’s Registered Antimicrobial Products Effective Against Norovirus (Norwalk-Like Virus)". 

Notes About This List

  • All EPA-registered pesticides must have an EPA registration number, which consists of a company number and a product number (e.g., 123-45). Alternative brand names have the same EPA registration number as the primary product.
  • When purchasing a product for use against a specific pathogen, check the EPA Reg. No. versus the products included on this list.
  • In addition to primary products, distributors may also sell products with formulations and efficacy identical to the primary products. Distributor products frequently use different brand names, but you can identify them by their three-part EPA registration number (e.g., 123-45-678, which represents a distributor product identical to the product example listed above, EPA Reg. No. 123-45).
  • If you would like to review the product label information for any of these products, please visit the EPA product label system.
  • Information about listed products is current as of the date on this list.

EPA Announced New Surface Disinfectant Products Added to List N in Effort to Combat COVID-19
The National Law Review | Saturday, April 4, 2020

On April 2, 2020, the U.S. Environmental Protection Agency (EPA) announced the addition of new surface disinfectants on EPA’s List N: Disinfectants for Use Against SARS-CoV-2 (List N) that may be used to combat SARS-CoV-2, the novel coronavirus that causes COVID-19. List N now contains 357 products. The webpage for List N also now has enhanced functionality to allow users to sort these products by surface type and use site. EPA states that it continues to expedite the review process for new disinfectants.

Previously, all products on List N had to have either an EPA emerging viral pathogen claim or have demonstrated efficacy against another human coronavirus. EPA now has expanded List N to include products on EPA’s List G: EPA’s Registered Antimicrobial Products Effective against Norovirus and List L: Products Effective against the Ebola Virus, as these products also meet EPA’s criteria for use against SARS-CoV-2.

EPA has updated List N to include the types of surfaces on which products can be used (e.g., hard or soft) and use sites (e.g., hospital, institutional or residential). Products applied via fogging or misting are now noted in the formulation column. This additional information allows the public to choose products that are appropriate for their specific circumstances.

Additionally, EPA has updated the Frequently Asked Questions (FAQ) EPA has posted about disinfectants related to coronavirus. The FAQ update provides new information on pesticide safety, enforcement, and pesticide devices. It also includes enhanced explanations of why List N products are qualified for use against SARS-CoV-2 and how these products can be used most effectively.

EPA states that it has continued to adapt its processes to ensure the supply of disinfectants keeps pace with demand. EPA recently announced additional flexibility that allows manufacturers of already-registered EPA disinfectants to obtain certain active and inert ingredients from any source of suppliers without prior approval by EPA. EPA also added 48 additional chemicals to its list of commodity inert ingredients. EPA states that this regulatory flexibility aims to help ease the production and availability of EPA-registered disinfectants.

EPA also is expediting all requests for company numbers and establishment numbers to enable new pesticide-producing establishments to come online as quickly as possible. 

Additional information on EPA’s efforts to address the novel coronavirus is available here.
