The final part consists of a single check digit or checksum that makes it easy to determine whether a CAS number is valid or not. The first part of the number, starting from the left, has up to 6 digits the second part has 2 digits. The CAS registry number includes up to 9 digits which are separated into 3 groups by hyphens (xxxxxx-xx-x). The Chemical Abstract Service (CAS) Registry Number is a unique identifier assigned to each chemical and to some mixtures of chemicals by the Chemical Abstracts Service, a division of the American Chemical Society.

Allow verification of InChI strings after network transmission. Make chemical structure database indexing easier Permit an InChI representation to be stored in fixed length fields Allow development of a web-based InChI lookup service Facilitate web searching, previously complicated by unpredictable breaking of InChI character strings by search engines The InChIKey specification was released in order to: The InChIKey, sometimes referred to as a hashed InChI, is a fixed length (25 character) condensed digital representation of the InChI that is not human-understandable. PubChem contains substance descriptions and small molecules with fewer than 1000 atoms and 1000 bonds. More than 80 database vendors contribute to the growing PubChem database.
Millions of compound structures and descriptive datasets can be freely downloaded via FTP.

PubChem can be accessed for free through a web user interface. The system is maintained by the National Center for Biotechnology Information (NCBI), a component of the National Library of Medicine, which is part of the United States National Institutes of Health (NIH). NIH Identifier (PubChem) is a database of chemical molecules. Given its non-unique nature, this SID field is no longer being used as the SID for PubChem submissions. It is used to ensure consistency of chemical information across DSSTox data files and for the population of new DSSTox data files. The EPA DSSTox Generic SID is used to aid in the central management of DSSTox structures and Standard Chemical Fields, and to provide look-across capability for common Test Substances across DSSTox files. It uniquely identifies each substance, enabling cross-walking between synonyms. The EPA SRS Identifier is an electronic key that facilitates data exchange with the Substance Registry System (SRS) and other EPA databases.

The EPA PC Code is sometimes referred to as the Shaugnessy Number. The EPA PC (Pesticide Chemical) Code is a unique chemical code number assigned by the EPA to a particular pesticide active ingredient, inert ingredient or mixture of active ingredients. To link directly to a substance user the following url pattern: : The EPA OPP Chemical ID is an internal identifier that can be used to directly link to any substance located in the Chemical Search Web Utility.
