138234-49-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138234-49-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,2,3 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138234-49:
(8*1)+(7*3)+(6*8)+(5*2)+(4*3)+(3*4)+(2*4)+(1*9)=128
128 % 10 = 8
So 138234-49-8 is a valid CAS Registry Number.

Biocatalytic Resolutions of Sulfinylalkanoates: A Facile Route to Optically Active Sulfoxides
Burgess, Kevin,Henderson, Ian,Ho, Kwok-Kan
, p. 1290 - 1295 (1992)
Two methods are presented for kinetic resolutions of compounds containing ester and sulfoxide functionalities (sulfinylalkanoates).In the first a crude lipase preparation from Pseudomonas sp. (K 10) mediates enantioselective hydrolysis of these esters in
