The CAS Registry Mumber 99641-27-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,4 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99641-27:
(7*9)+(6*9)+(5*6)+(4*4)+(3*1)+(2*2)+(1*7)=177
177 % 10 = 7
So 99641-27-7 is a valid CAS Registry Number.

Benzo-Fused Bicyclic Imides

Pavia, Michael R.,Moos, Walter H.,Hershenson, Fred M.

, p. 560 - 564 (1990)

The benzo-fused bicyclic imides, 2 and 3, were synthesized via acetic anhydride promoted ring closure of lactam acids 10 and 15.Attempts to carry out the analogous reaction with lactam acid 21 failed to afford the desired 5,5-benzo-fused bicyclic imide 4.Possible reasons for the failure of this reaction are discussed.
