Check Digit Verification of cas no

The CAS Registry Mumber 124990-55-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,9,9 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 124990-55:
(8*1)+(7*2)+(6*4)+(5*9)+(4*9)+(3*0)+(2*5)+(1*5)=142
142 % 10 = 2
So 124990-55-2 is a valid CAS Registry Number.

Biocatalytic Resolutions of α-Methylene-β-hydroxy Esters and Ketones

Burgess, Kevin,Jennings, Lee D.

, p. 1138 - 1139 (1990)

α-Methylene-β-hydroxy esters and ketones are resolved via lipase mediated irreversible acylations; experiments with a range of substrates have been used to identify factors that influence the enantioselection obtained and reaction times required.
