The CAS Registry Mumber 172877-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,8,7 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 172877-91:
(8*1)+(7*7)+(6*2)+(5*8)+(4*7)+(3*7)+(2*9)+(1*1)=177
177 % 10 = 7
So 172877-91-7 is a valid CAS Registry Number.

, p. 2663 - 2666 (2007/10/02)

Friedel-Crafts acylation of 2-methyl-1-phenylsulfonylindole 6 gave the 3-acyl derivatives 7 which upon side chain bromination with N-bromosuccinimide (NBS) followed by treatment with primary amines afforded the title compounds 9.Diels-Alder reaction of 9 with dimethyl acetylenedicarboxylate (DMAD) gave the polysubstituted carbazoles 12.
