Check Digit Verification of cas no

The CAS Registry Mumber 87351-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,3,5 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87351-40:
(7*8)+(6*7)+(5*3)+(4*5)+(3*1)+(2*4)+(1*0)=144
144 % 10 = 4
So 87351-40-4 is a valid CAS Registry Number.

Chemistry of Substituted (α-Carbethoxyvinyl)cuprates. 2. Stereospecific Olefin Synthesis

Marino, Joseph P.,Linderman, Russell J.

, p. 4621 - 4628 (2007/10/02)

The reactivity of substituted (α-carbethoxyvinyl)cuprate reagents with various electrophiles has been studied systematically.The reaction of this type of cuprate reagent with ketones and epoxides leads to high yields of isomerically pure olefinic esters, while its condensation reaction with aldehydes produced mixtures of isomers.The stereochemistry of the condensation reaction with carbonyl compounds is explained by a steric control mechanism involving an allenoate intermediate.
