Check Digit Verification of cas no

The CAS Registry Mumber 880762-08-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,0,7,6 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 880762-08:
(8*8)+(7*8)+(6*0)+(5*7)+(4*6)+(3*2)+(2*0)+(1*8)=193
193 % 10 = 3
So 880762-08-3 is a valid CAS Registry Number.

Tetrabutylammonium pyridin-2-olate: A new reagent for the efficient synthesis of N-aryl pyridin-2-ones

Zhang, Huiping,Chen, Bang-Chi,Wang, Bei,Chao, Sam T.,Zhao, Rulin,Lim, Ngiapkie,Balasubramanian, Balu

experimental part, p. 1523 - 1526 (2009/04/06)

A new reagent, tetrabutylammonium pyridin-2-olate, was prepared and its application to the efficient synthesis of N-aryl pyridine-2-ones was demonstrated using CuI-catalyzed coupling reactions with aryl iodides. This coupling reaction is mild, high-yielding, and remarkably chemoselective (N- vs. O-arylation). It is also compatible with substrates containing labile functional groups.
