Dialog "How Do I...?" - Chemistry & Toxicology

Locate Current Literature References for a Chemical?

TOPIC: Dialog has a number of OneSearch® categories that contain CAS® Registry Numbers to use in searching for chemical literature references. Some of the databases included in the RNMED medical category include: NTIS (File 6), EMBASE® (File 73), International Pharmaceutical Abstracts (File 74) and MEDLINE® (File 155). The chemical RNCHEM category includes: Chapman & Hall Chemical Database (File 303) and The Merck Index Online (File 304) and Registry of Toxic Effects of Chemical Substances (RTECS®) (File 336).

The MAP command is a powerful command that extracts search terms from a specific field in a record or group of records and creates a SearchSave. The SearchSave can be permanent or temporary and can be executed in the same or different Dialog files.You can MAP Registry Numbers (RN) (e.g., MAP RN TEMP). You can MAP synonyms (SY) (e.g., MAP SY TEMP), and you can MAP both Registry Numbers (RN) and synonyms (SY) at the same time (e.g., MAP SYRN TEMP).

Note: The TEMP at the end of the MAP command indicates that the SearchSave is temporary and will be saved for 7 days at no charge.

In this search we'll find the CAS Registry Number for carbon tetrachloride and MAP the Registry Number(s) and synonyms to chemical literature files including Analytical Abstracts (File 305) Embase® (File 72) and MEDLINE® (File 72) to retrieve comprehensive answers.
