1272665-68-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1272665-68-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,2,6,6 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1272665-68:
(9*1)+(8*2)+(7*7)+(6*2)+(5*6)+(4*6)+(3*5)+(2*6)+(1*8)=175
175 % 10 = 5
So 1272665-68-5 is a valid CAS Registry Number.

Palladium-catalyzed amidation of 2-chloropyrimidines
Vimolratana, Marc,Simard, Jillian L.,Brown, Sean P.
experimental part, p. 1020 - 1022 (2011/03/20)
A mild and efficient Pd-catalyzed coupling of amides with 2-chloropyrimidines is described. The use of bidentate phosphines, such as Xantphos (7), as supporting ligands was found to be crucial for providing high yields of 2-(N-acylamino)pyrimidine couplin
