136031-73-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136031-73-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,0,3 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 136031-73:
(8*1)+(7*3)+(6*6)+(5*0)+(4*3)+(3*1)+(2*7)+(1*3)=97
97 % 10 = 7
So 136031-73-7 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 (2007/10/02)
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
