Check Digit Verification of cas no

The CAS Registry Mumber 1256237-21-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,2,3 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1256237-21:
(9*1)+(8*2)+(7*5)+(6*6)+(5*2)+(4*3)+(3*7)+(2*2)+(1*1)=144
144 % 10 = 4
So 1256237-21-4 is a valid CAS Registry Number.

Complete regio- and stereoselective construction of highly substituted silyl enol ethers by three-component coupling

Tsubouchi, Akira,Enatsu, Shouko,Kanno, Ryo,Takeda, Takeshi

, p. 7089 - 7091 (2010)

Three components for total control: Trisubstituted silyl enol ethers were prepared by three-component coupling of α-silyl α, β-unsaturated ketones, organocopper reagents, and organic halides with complete regio- and stereoselectivity (see scheme). The reaction proceeded through a 1,3 migration of the silyl group via cyclic silicate intermediates, which controlled the configuration of the silyl enol ethers.
