1139719-64-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1139719-64-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,9,7,1 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1139719-64:
(9*1)+(8*1)+(7*3)+(6*9)+(5*7)+(4*1)+(3*9)+(2*6)+(1*4)=174
174 % 10 = 4
So 1139719-64-4 is a valid CAS Registry Number.

Alkenylation of arylamines and N-arylacetamides with acetylene compounds in superacids
Shchukin,Vasil'ev,Aristov,Fukin,Rudenko
experimental part, p. 965 - 979 (2009/06/18)
Vinyl type cations generated in superacid HSO3F by the protonation of the triple bond of acetylene compounds efficiently react with arylammonium ions and N-arylacetamides yielding alkenylation products of the aromatic rings in the given amino d
