Description:

Coverage: 1907 to the present File Size: More than 96,9 million records, including over 59,7 million sequences (7/2008) Updates: Daily File Type: Structure Content: Chemical substances Language: English CASRNs Y The CAS REGISTRY File is a substance database containing records for substances identified by the Chemical Abstracts Service (CAS) Registry System. These include substances indexed in CAplusSM, CASM, and CAOLDSM files, and special registrations, for example, registrations for regulatory lists such as TSCA and EINECS.
All substance records contain a unique CAS REGISTRY Number®. Substance records may also have CA index names, synonyms, molecular formulas, alloy composition tables, classes for polymers, nucleic acid and protein sequences, ring analysis data, and structure diagrams, all of which are searchable and displayable. In addition to substance information, REGISTRY records contain super roles and document type information from CAplus, experimental and predicted (calculated) property data as well as tags pointing to references containing experimental property data.
Also displayable in the REGISTRY File are the 10 most recent CA references citing the substance since 1907, the total number of records citing the substance in the CAplus, CA, and CAOLD, and the total number of records in the CA File for the non-specific derivatives.
LREGISTRY is the companion training file for learning how to use the REGISTRY File.
