Check Digit Verification of cas no
The CAS Registry Mumber 130179-05-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,1,7 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 130179-05:
(8*1)+(7*3)+(6*0)+(5*1)+(4*7)+(3*9)+(2*0)+(1*5)=94
94 % 10 = 4
So 130179-05-4 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
