Check Digit Verification of cas no

The CAS Registry Mumber 157099-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,0,9 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 157099-89:
(8*1)+(7*5)+(6*7)+(5*0)+(4*9)+(3*9)+(2*8)+(1*9)=173
173 % 10 = 3
So 157099-89-3 is a valid CAS Registry Number.

Radical Translocation Reactions across Amides. 1,5-Hydrogen-Transfer Reactions of o-Iodobenzamides and N-(o-Iodobenzyl) Amides

Curran, Dennis P.,Liu, Hohgtao

, p. 1377 - 1394 (2007/10/02)

Radicals derived from N,N-disubstituted o-iodobenzamides undergo rapid 1,5-hydrogen-transfer reactions.The regioselectivity of these reactions is coupled to the rotamer population of the starting iodobenzamide, and the products vary with changing amide substituents.Related 1,5-hydrogen-transfer reactions are observed for N-alkyl-N-(o-iodobenzyl)-benzamides and -acetamides.
