4271-48-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4271-48-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,7 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4271-48:
(6*4)+(5*2)+(4*7)+(3*1)+(2*4)+(1*8)=81
81 % 10 = 1
So 4271-48-1 is a valid CAS Registry Number.

Nucleophile-mediated oxa-Michael addition reactions of divinyl sulfone - a thiol-free option for step-growth polymerisations
Strasser, Simone,Slugovc, Christian
, p. 5091 - 5094 (2015/11/27)
Triphenylphosphine and 4-dimethylaminopyridine promote the oxa-Michael addition reaction of alcohols and divinyl sulfone. Under solvent-free conditions, the reaction is particularly fast and allows for the preparation of polymers.
