Check Digit Verification of cas no

The CAS Registry Mumber 649136-02-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,9,1,3 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 649136-02:
(8*6)+(7*4)+(6*9)+(5*1)+(4*3)+(3*6)+(2*0)+(1*2)=167
167 % 10 = 7
So 649136-02-7 is a valid CAS Registry Number.

Study of the Lewis acid-promoted addition of silylenol ethers to imines derived from glyceraldehyde

Badorrey, Ramon,Cativiela, Carlos,Diaz-de-Villegas, Maria D.,Galvez, Jose A.

, p. 9189 - 9192 (2007/10/03)

Chiral N-benzylimines derived from D-glyceraldehyde undergo Lewis acid-promoted asymmetric Mannich reactions with O-methyl-O-trimethylsilyl dimethylketeneacetal to give β-amino acid esters in good yields and with excellent diastereoselectivities.
