What is CAS REGISTRY?
​CAS REGISTRY is the most authoritative collection of disclosed chemical substance information, containing more than 126 million organic and inorganic substances and 66 million sequences.
CAS REGISTRY covers substances identified from the scientific literature from 1957 to the present, with additional substances going back to the early 1900s.

What is a CAS Registry Number (CAS)?

Each CAS Registry Number®  identifier:

• Is a unique numeric identifier
• Designates only one substance
• Has no chemical significance
• Is a link to a wealth of information about a specific chemical substance

What does a CAS Registry Number look like?
A CAS Registry Number is a numeric identifier that can contain up to 10 digits, divided by hyphens into three parts.
The right-most digit is a check digit used to verify the validity and uniqueness of the entire number.
For example, 58-08-2 is the CAS Registry Number for caffeine.

How does CAS assign Registry Numbers?
A CAS Registry Number is assigned to a substance when it enters the CAS REGISTRY database. Numbers are assigned in sequential order to unique, new substances identified by CAS scientists for inclusion in the database.

What kinds of compounds does the CAS REGISTRY contain?CAS REGISTRY contains a wide variety of substances, including the world's largest collection of:

• Organic compounds
• Inorganic compounds
• Metals
• Alloys
• Minerals
• Coordination compounds
• Organo-metalics
• Elements
• Isotopes
• Nuclear particles
• Proteins and nucleic acids
• Polymers
• Non-structurable materials (UVCBs)

How frequently is the CAS REGISTRY database updated?

Approximately 15,000 new substances are added each day.


Why have CAS Registry Numbers become the world standard?

Since CAS Registry Numbers are not dependent upon any system of chemical nomenclature, they can:

• Provide a reliable common link between the various nomenclature terms used to describe substances
• Serve as an international resource for chemical substance identifiers used by scientists, industry and regulatory bodies

Why do regulatory agencies rely on CAS Registry Numbers?
Chemical compounds can be described in many different ways:

• Molecular formula
• Structure diagram
• Systematic names
• Generic names
• Proprietary or trade names
• Trivial names

A CAS Registry Number, however, is unique and specific to only one substance regardless of how many other ways the substance can be described.
Governmental agencies have found CAS Registry Numbers ideal for keeping track of substances because 

• They are unique
• They can be validated quickly and reliably
• They are internationally recognized

Where can I find CAS REGISTRY Numbers?

Find CAS Registry Numbers in:

• SciFinder®
• STN® databases
• CAS publications
• Other publications 
  • Governmental regulatory agency commercial chemical inventories
  • Selected Elsevier databases
  • Handbooks, guides and technical reports
  • Other printed reference works
  • Chemical catalogs
