Check Digit Verification of cas no

The CAS Registry Mumber 1263816-72-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,8,1 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1263816-72:
(9*1)+(8*2)+(7*6)+(6*3)+(5*8)+(4*1)+(3*6)+(2*7)+(1*2)=163
163 % 10 = 3
So 1263816-72-3 is a valid CAS Registry Number.

Lewis acid-catalyzed nucleophilic ring-opening/intramolecular Conia-ene reactions of methylenecyclopropane 1,1-diesters with propargyl alcohols

Hu, Bao,Ren, Jun,Wang, Zhongwen

experimental part, p. 763 - 768 (2011/03/19)

We presented a Lewis acid-catalyzed nucleophilic ring opening of methylenecyclopropane (MCP) 1,1-diesters with propargyl alcohols. Unlike the proximal-bond cleavage mode observed in cases of unactivated MCPs, the intrinsic characteristic of MCP 1,1-dieste
