Check Digit Verification of cas no

The CAS Registry Mumber 1272665-71-0 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, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1272665-71:
(9*1)+(8*2)+(7*7)+(6*2)+(5*6)+(4*6)+(3*5)+(2*7)+(1*1)=170
170 % 10 = 0
So 1272665-71-0 is a valid CAS Registry Number.

N-Methylamino Pyrimidyl Amides (MAPA): Highly Reactive, Electronically-Activated Amides in Catalytic N-C(O) Cleavage

Meng, Guangrong,Lalancette, Roger,Szostak, Roman,Szostak, Michal

, p. 4656 - 4659 (2017)

Despite recent progress in catalytic cross-coupling technologies, the direct activation of N-alkyl-N-aryl amides has been a challenging transformation. Here, we report the first Suzuki cross-coupling of N-methylamino pyrimidyl amides (MAPA) enabled by the controlled nN → πAr conjugation and the resulting remodeling of the partial double bond character of the amide bond. The new mode of amide activation is suitable for generating acyl-metal intermediates from unactivated primary and secondary amides.
