Check Digit Verification of cas no

The CAS Registry Mumber 100420-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,4,2 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 100420-03:
(8*1)+(7*0)+(6*0)+(5*4)+(4*2)+(3*0)+(2*0)+(1*3)=39
39 % 10 = 9
So 100420-03-9 is a valid CAS Registry Number.

HIGHLY ENANTIOSELECTIVE SYNTHESIS OF ANTI(THREO)-ALDOLS BY THE ASYMMETRIC ALDOL REACTION UTILIZING A CHIRAL AZAENOLATE

Narasaka, Koichi,Miwa, Tetsuo

, p. 1217 - 1220 (1985)

Diastereo- and enantioselective aldol reaction between 3-pentanone and aldehydes is achieved utilizing a chiral oxazolidine derived from 3-pentanone and chiral norephedrine.The reaction of a tin(II) azaenolate generated from the chiral oxazolidine with aldehydes affords predominantly anti(threo)-aldols of high enantiomeric purity.
