To further improve the newest STNext database, a number of enhancements to CAS FORMULATIONS have been released. These include:

  • More Indented display formats – In addition to IBIB, the ICHEM, IPRODUCT, ICHPR and IALL display formats are now also available. In these formats, field codes are replaced by their explanation (e.g., instead of IN, INVENTOR).
  • More values in the FA (Field Availability) field: Component Name (CNM/FA), Formulation Description (FD/FA), Product Name Type Value (PNV/FA), Group Vocabulary (GVO/FA), Component Vocabulary (CVO/FA), Registry Number (RN/FA), Group Function (GFU/FA), and Component Function (CFU/FA). Search CNM/FA to find records which include information in the CNM field.
  • Search for Registry Numbers in the RN supersearch field. Enter an RN of interest, and the results will be provided for postings in the Group RN (/GRPRN) field, the Component RN (/CMPRN) field and the Solvent RN (/SOLRN) field. (Solvent RNs identify substances that must be added to a formulation to activate it into a product, and are distinct from solvents which may be part of a formulation.)
