Check Digit Verification of cas no

The CAS Registry Mumber 71925-83-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,2 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 71925-83:
(7*7)+(6*1)+(5*9)+(4*2)+(3*5)+(2*8)+(1*3)=142
142 % 10 = 2
So 71925-83-2 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 (1985)

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

REDUCTION OF β-KETOSULFOXIDES : A HIGHLY EFFICIENT ASYMMETRIC SYNTHESIS OF BOTH ENANTIOMERS OF METHYL CARBINOLS FROM THE CORRESPONDING ESTERS

Solladie, Guy,Greck, Christine,Demailly, Gilles,Solladie-Cavallo, Arlette

, p. 5047 - 5050 (2007/10/02)

It is shown that reductions of β-ketosulfoxides of identical chirality (R) at sulfur, lead to reduction products of opposite stereochemistry according to the reducing agent used.The high enantiomeric excesses obtained (80 to 100percent) provide a general route to both enantiomers of methylcarbinols from the corresponding esters.
