Check Digit Verification of cas no

The CAS Registry Mumber 97240-66-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,2,4 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 97240-66:
(7*9)+(6*7)+(5*2)+(4*4)+(3*0)+(2*6)+(1*6)=149
149 % 10 = 9
So 97240-66-9 is a valid CAS Registry Number.

Highly Diastereoselective Reduction of Chiral β-Ketosulphoxides under Chelation Control: Application to the Synthesis of (R)-(+)-n-Hexadecano-1,5-lactone

Kosugi, Hiroshi,Konta, Hiroshi,Uda, Hisashi

, p. 211 - 213 (2007/10/02)

The presence of zinc chloride in the reduction of chiral β-ketosulphoxides with di-isobutylaluminium hydride effects high 1,3-asymmetric induction to give β-hydroxysulphoxides; this method can be successfully applied to the synthesis of optically pure 1,4
