Database: REGISTRY

CAS REGISTRY is the most authoritative collection of disclosed chemical substance information. Each substances record is identified by a unique CAS Registry Number.

Records may include CA index names, synonyms, molecular formulas, alloy composition tables, classes for polymers and protein and nucleic acid sequences, ring analysis data, and structure diagrams, all of which are searchable and displayable. Records may also contain super roles and document type information from CAplusSM, experimental property data and tags, predicted property data, and experimental carbon-13 NMR, proton NMR, mass, and IR absorption spectra. Also displayable are the 10 most recent CA references citing the substance since 1907, the total number of records citing the substance in CAplus and CASM, and the total number of records in CA for the nonspecific derivatives.

LREGISTRY is the companion training file for learning how to use the REGISTRY File.

File Data
