Check Digit Verification of cas no

The CAS Registry Mumber 135980-98-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,9,8 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 135980-98:
(8*1)+(7*3)+(6*5)+(5*9)+(4*8)+(3*0)+(2*9)+(1*8)=162
162 % 10 = 2
So 135980-98-2 is a valid CAS Registry Number.

Highly enantioselective routes to Darzens and acetate aldol products from achiral aldehydes and t-butyl bromoacetate

Corey,Choi

, p. 2857 - 2860 (1991)

New methodology is described for the enantioselective coupling of t-butyl bromoacetate with aldehydes to give anti-α-bromo β-hydroxy esters (1), useful precursors of chiral glycidic esters (2), acetate aldols (3), β-amino acid esters (4) and α-amino acid
