Check Digit Verification of cas no
The CAS Registry Mumber 130214-76-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,1 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 130214-76:
(8*1)+(7*3)+(6*0)+(5*2)+(4*1)+(3*4)+(2*7)+(1*6)=75
75 % 10 = 5
So 130214-76-5 is a valid CAS Registry Number.

A simple and versatile synthesis of substituted ethynesulfonamides
LeClercq,Brienne
, p. 3875 - 3878 (2007/10/02)
A variety of substituted 2-arylethynesulfonamides were prepared by a two-step sequence: 1. preparation of 2-oxo-2-arylethanesulfonamides by reaction of the appropriate methanesulfonamide carbanion with a substituted benzoic ester, 2. dehydration of the re
