title: On-line storage and retrieval of chemical information. I. Structure entry.
abstract: An interactive program has been developed for entering, verifying, and storing chemical structures encoded in the Wiswesser Line Notation. The program calculates a molecular formula from the WLN for checking and then generates a bit string fragment code and connection table of the atoms in the structure. The encoding and entry of the WLN using a CRT has significantly improved the speed of the total compound registration process.
