Check Digit Verification of cas no

The CAS Registry Mumber 145297-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,2,9 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 145297-30:
(8*1)+(7*4)+(6*5)+(5*2)+(4*9)+(3*7)+(2*3)+(1*0)=139
139 % 10 = 9
So 145297-30-9 is a valid CAS Registry Number.

C-H arylation of pyridines: High regioselectivity as a consequence of the electronic character of C-H bonds and heteroarene ring

Guo, Pengfei,Joo, Jung Min,Rakshit, Souvik,Sames, Dalibor

supporting information; experimental part, p. 16338 - 16341 (2011/11/29)

We report a new catalytic protocol for highly selective C-H arylation of pyridines containing common and synthetically versatile electron-withdrawing substituents (NO2, CN, F and Cl). The new protocol expands the scope of catalytic azine functi
