Check Digit Verification of cas no

The CAS Registry Mumber 1289643-09-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,9,6,4 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1289643-09:
(9*1)+(8*2)+(7*8)+(6*9)+(5*6)+(4*4)+(3*3)+(2*0)+(1*9)=199
199 % 10 = 9
So 1289643-09-9 is a valid CAS Registry Number.

Asymmetric synthesis of α-amino acids by reduction of N-tert-butanesulfinyl ketimine esters

Reddy, Leleti Rajender,Gupta, Aditya P.,Liu, Yugang

experimental part, p. 3409 - 3415 (2011/06/25)

A highly regio- and diastereoselective reduction of various N-tert-butanesulfinyl ketimine esters with L-Selectride resulting in the formation of α-amino acids is reported. This method is quite general and also practical for the preparation of both enantiomers of aryl or aliphatic α-amino acids in high yields.
