Check Digit Verification of cas no

The CAS Registry Mumber 74965-16-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,6 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74965-16:
(7*7)+(6*4)+(5*9)+(4*6)+(3*5)+(2*1)+(1*6)=165
165 % 10 = 5
So 74965-16-5 is a valid CAS Registry Number.

Preparation and Bromination of a 3a,6-Dihydroindole

Noland, Wayland E.,Kim, Keun Jae,Lee, Chang Kiu,Bae, Sun Kun,Hahn, Chi Sun

, p. 4582 - 4584 (1980)

A 3a,6-dihydroindole was prepared by the Diels-Alder addition of dimethyl acetylenedicarboxylate to dimethyl maleate. Subsequent reaction with bromine gave a 2,3-dibromoindoline which is different from that obtained from the corresponding 3a,7a-dihydroindole.
