Check Digit Verification of cas no

The CAS Registry Mumber 193979-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,9,7 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 193979-97:
(8*1)+(7*9)+(6*3)+(5*9)+(4*7)+(3*9)+(2*9)+(1*7)=214
214 % 10 = 4
So 193979-97-4 is a valid CAS Registry Number.

Aziridine 2-carboxylate ester mediated asymmetric synthesis of α-alkyl β-amino acids

Davis, Franklin A.,Reddy, G. Venkat,Liang, Chang-Hsing

, p. 5139 - 5142 (1997)

The highly stereoselective ring opening of N-tosylaziridine 2-carboxylate esters with LiAIH4 followed by oxidation of the ensuing syn alcohols results in a highly efficient 4 step asymmetric synthesis of α-methyl β-amino acids from N-sulfinylaziridine 2-carboxylate esters.
