Introduction
CAS REGISTRY is a is a CAS database (like CAplus, CASREACT, CHEMCATS, CHEMLIST, CIN, and MARPAT) containing more than 63 million organic and inorganic substances and 63 million sequences from scientific literature from 1957 to the present, with additional substances going back to 1907.[1][2] Substances in the CAS REGISTRY include compounds like:[1]
- Organic compounds
- Inorganic compounds
- Metals
- Alloys
- Minerals
- Coordination compounds
- Organometallics
- Elements
- Isotopes
- Nuclear particles
- Proteins and nucleic acids
- Polymers
- Nonstructurable materials (UVCBs)
Records contain the following searchable fields:[2]
- CAS Registry Numbers
- CA index names
- Commonly used synonyms
- Polymer class terms
- Structure diagrams (displayable, with searchable stereo-chemical information)
- Molecular formulas
- Calculated physical properties
- Total number of citations to substances in the CA and CAplus files
Particular record types are also searchable by substance-specific criteria:[2]
Substances containing rings may be retrieved using ring system data; alloys may be retrieved using alloy composition information; polymers may be retrieved using polymer class terms; and protein and nucleic acid sequences may be retrieved using codes for the amino acids or nucleotides. Sequence homology searching is provided through the BLAST® program.
CAS REGISTRY is accessible through STN and SciFinder, and many other STN databases, CD-ROM products, CAS printed publications, and other publications are labeled with CAS REGISTRY numbers.[1] Each REGISTRY number is a unique numeric identifier that identifies one substance.[1] CAS REGISTRY is updated daily with about 12,000 new substances.[1]
