Description:

ZREGISTRY has zero connect hour pricing.

The ZREGISTRY is a substance database containing records for substances identified by the Chemical Abstracts Service (CAS) Registry System. These include substances indexed in CAplus^SM, CA^SM, and CAOLD^SM files, and special registrations, for example, registrations for regulatory lists such as TSCA and EINECS.

All substance records contain a unique CAS REGISTRY Number® and index name. Substance records may also have 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, ZREGISTRY 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 ZREGISTRY 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 ZREGISTRY File.

Left truncation is available in the Chemical Name Segment (/CNS), Editor Note (/ENTE), and Notes (/NTE) fields.
