Chemical Structure/Reaction Searches
google

Chemical structure and chemical reaction searches are accomplished on the Chemical Abstracts (CAS) databases through STN. Searching structures involves creating a graphic structure to identify an exact match or similar structures. The display of large numbers of bibliographic records for patents or articles resulting from a structure search on STN may be expensive in terms of computer charges, and a major part of the cost.

Cost: $85/ hour x 2-5 hours, depending on complexity. $170 to $425 plus computer charges, which are considerable.
