Check Digit Verification of cas no

The CAS Registry Mumber 322765-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,2,7,6 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 322765-91:
(8*3)+(7*2)+(6*2)+(5*7)+(4*6)+(3*5)+(2*9)+(1*1)=143
143 % 10 = 3
So 322765-91-3 is a valid CAS Registry Number.

One-pot AgOAc-mediated synthesis of polysubstituted pyrroles from primary amines and aldehydes: Application to the total synthesis of purpurone

Li, Qingjiang,Fan, Aili,Lu, Zhiyao,Cui, Yuxin,Lin, Wenhan,Jia, Yanxing

supporting information; experimental part, p. 4066 - 4069 (2010/11/16)

A simple and efficient method for the synthesis of 1,3,4-trisubstituted or 3,4-disubstituted pyrroles has been developed. The reaction represents the first time that pyrroles are synthesized directly from readily available aldehydes and amines (anilines)

First total synthesis of the marine alkaloids purpurone and ningalin C

Peschko,Steglich

, p. 9477 - 9481 (2007/10/03)

Purpurone is obtained from 3-(3,4-dimethoxyphenyl)pyruvic acid, 2-(4-methoxyphenyl)ethylamine and 2',2',2'-trichloroethyl 2-bromo-2-(3,4-dimethoxyphenyl)acetate in seven steps with an overall yield of 11%. Ningalin C is synthesized from 1-[2-(3,4-dimethox
