Check Digit Verification of cas no

The CAS Registry Mumber 123394-78-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,3,9 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 123394-78:
(8*1)+(7*2)+(6*3)+(5*3)+(4*9)+(3*4)+(2*7)+(1*8)=125
125 % 10 = 5
So 123394-78-5 is a valid CAS Registry Number.

ENANTIOSELECTIVE SYNTHESIS OF 2-BENZYLOXY ALCOHOLS AND 1,2-DIOLS VIA ALKYLATION OF CHIRAL GLYCOLATE IMIDES. A CONVENIENT APPROACH TO OPTICALLY ACTIVE GLYCEROL DERIVATIVES

Cardillo, Giuliana,Orena, Mario,Romero, Marta,Sandri, Sergio

, p. 1501 - 1508 (2007/10/02)

The alkylation of the chiral enolates of glycolate imides 2a and 2b proceedes in highly diastereoselective manner to give 2'-substituted products in good yield.Reductive cleavage with LiBH4 affords the corresponding 2-benzyloxyalcohols 3a-c and 11a-b which are successively converted to 1,2-diols in high optical purity.By this method (R)-1-propanoyloxy-2,3-propanediol 9 and (S)-1-tridecyloxy-2,3-propanediol 14, a glyceride extracted from sponges Plocamiidae, have been synthesized, starting from 2a and 2b, respectively.
