THE IMPLEMENTATION OF ATOM-ATOM MAPPING AND RELATED FEATURES IN THE REACTION ACCESS SYSTEM (REACCS)... 

With a full-featured reaction indexing system such as the Reaction Access System (REACCS), there exists a wide variety of criteria for creating such a review. Table 1...

MDL Information Systems, Inc. MDL provides modular software systems for managing chemical information, as weU as related molecular and reaction databases for use with the software. MDL s database management programs, MACCS-II and REACCS, provide access to compound and reaction databases and also have the capabiHty to manage user-created databases (37). Although MDL is not considered to be an on-line database vendor, it is mentioned here because of the value of its information products and services to the chemical industry. 

While for a long time the in-house reaction-retrieval system market was dominated by REACCS and ISIS, with almost every reaction database being available in the REACCS/ISIS format, there are now a number of competitors. Some of the Synopsys reaction databases can be run on Synopsys Accord, a structure- and reaction-handling add-on for Microsoft Access and Excel. Chem-X, a modular software system from Chemical Design Ltd. includes (since April 1993) the reaction... 

Eastman Kodak has many laboratories worldwide, all with their own information departments, but the Information and Computer Technology Division in Rochester, and in particular the Application and Data Resources Unit, is responsible for the 555,000 compounds in the Chemical Registry System (under both MACCS and CAS Registry System software). There are also on file 17000 reactions under REACCS, 190,000 reports and 65,000 patents in a photographic patents index. The Chemical Information Centre holds 1,100,000 index cards, half of them in accession number order and half in molecular formula sequence.
