Check Digit Verification of cas no

The CAS Registry Mumber 163444-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,4,4 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 163444-20:
(8*1)+(7*6)+(6*3)+(5*4)+(4*4)+(3*4)+(2*2)+(1*0)=120
120 % 10 = 0
So 163444-20-0 is a valid CAS Registry Number.

Amide-based protecting/radical translocating (PRT) groups. Generation of radicals adjacent to carbonyls by 1,5-hydrogen transfer reactions of o-iodoanilides

Curran, Dennis P.,Yu, Hosung,Liu, Hongtao

, p. 7343 - 7366 (2007/10/02)

The o-iodoanilide group is shown to be broadly useful for the generation and subsequent reactions of radicals adjacent to carboxyl groups. The results indicate that this group is one of the best 'protecting/radical translocating' (PRT) groups introduced t
