1319744-22-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1319744-22-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,9,7,4 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1319744-22:
(9*1)+(8*3)+(7*1)+(6*9)+(5*7)+(4*4)+(3*4)+(2*2)+(1*2)=163
163 % 10 = 3
So 1319744-22-3 is a valid CAS Registry Number.

Palladium-catalyzed direct ethynylation of C(sp3)-H bonds in aliphatic carboxylic acid derivatives
Ano, Yusuke,Tobisu, Mamoru,Chatani, Naoto
, p. 12984 - 12986 (2011/10/05)
The first catalytic alkynylation of unactivated C(sp3)-H bonds has been accomplished. The method allows for the straightforward introduction of an ethynyl group into aliphatic acid derivatives under palladium catalysis. This new reaction can be
