Check Digit Verification of cas no

The CAS Registry Mumber 114418-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,4,1 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 114418-49:
(8*1)+(7*1)+(6*4)+(5*4)+(4*1)+(3*8)+(2*4)+(1*9)=104
104 % 10 = 4
So 114418-49-4 is a valid CAS Registry Number.

A NOVEL METHOD FOR THE STEREOSELECTIVE SYNTHESIS OF Β-AMINOACID DERIVATIVES VIA TIN(II) CARBOXYLIC THIOESTER ENOLATES

Yamasaki, Noritsugu,Murakami, Masahiro,Mukaiyama, Teruaki

, p. 1013 - 1016 (1986)

Tin(II) carboxylic thioester enolates, formed in situ from stannous 2-methyl-2-propanethiolate and ketenes, react with imines in the presence of stannous triflate to give the corresponding β-aminocarboxylic thioesters in an anti-selective manner.This method is successfully applied to a diastereoselective synthesis of a carbapenem antibiotic PS-5 intermediate.
