Check Digit Verification of cas no

The CAS Registry Mumber 623157-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,3,1,5 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 623157-95:
(8*6)+(7*2)+(6*3)+(5*1)+(4*5)+(3*7)+(2*9)+(1*5)=149
149 % 10 = 9
So 623157-95-9 is a valid CAS Registry Number.

Silver acetate-catalysed asymmetric 1,3-dipolar cycloadditions of imines and chiral acrylamides

Nyerges, Miklós,Bendell, David,Arany, Andrea,Hibbs, David E.,Coles, Simon J.,Hursthouse, Michael B.,Groundwater, Paul W.,Meth-Cohn, Otto

, p. 3745 - 3753 (2007/10/03)

N-Metallated azomethine ylides were generated by the reaction of arylidene glycine imines with AgOAc and triethylamine. These azomethine ylides undergo cycloaddition to chiral acrylamides with excellent diastereoselectivity. The configuration of two of the cycloadducts was confirmed by X-ray crystallography.
