Check Digit Verification of cas no

The CAS Registry Mumber 163776-49-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,7,7 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 163776-49:
(8*1)+(7*6)+(6*3)+(5*7)+(4*7)+(3*6)+(2*4)+(1*9)=166
166 % 10 = 6
So 163776-49-6 is a valid CAS Registry Number.

Asymmetric approaches to 1,2-disubstituted mitosenes based on the intramolecular cyclization of diazoesters

Lee, Sangku,Lim, Hee-Jong,Cha, Kobpurn Lulu,Sulikowski, Gary A.

, p. 16521 - 16532 (2007/10/03)

A strategy for the asymmetric synthesis of 1,2-disubstituted mitosenes is described. The key reaction is the decomposition of a meso diazoester in the presence of chiral copper(I) catalysts. Cyclization of diazoesters derived from (1R, 2S, 5R)-menthol and
