Check Digit Verification of cas no

The CAS Registry Mumber 62251-79-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,2,5 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 62251-79:
(7*6)+(6*2)+(5*2)+(4*5)+(3*1)+(2*7)+(1*9)=110
110 % 10 = 0
So 62251-79-0 is a valid CAS Registry Number.

Versatile Route to Substituted Ketones through Charge-Directed Conjugate Addition Reactions

Cooke, Manning P.

, p. 4963 - 4968 (2007/10/02)

Charge-directed conjugate addition reactions have been applied to the preparation of highly substituted ketones.Acylphosphoranes resulting from conjugate addition-alkylation reactions are reduced by Al-Hg to β-keto esters, which, upon alkylation and hydrolysis, give ketones in high yields.An application of this methodology to the synthesis of 9, the defense substance of L. longipes, is described.
