149817-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149817-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,8,1 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 149817-40:
(8*1)+(7*4)+(6*9)+(5*8)+(4*1)+(3*7)+(2*4)+(1*0)=163
163 % 10 = 3
So 149817-40-3 is a valid CAS Registry Number.

FACILE PRODUCTION AND CYCLIZATIONS OF AMIDYL RADICALS
Newcomb, Martin,Esker, John L.
, p. 1035 - 1038 (2007/10/02)
Amides were converted via imidoyl chlorides into N-hydroxypyridine-2-thione imidate esters that were precursors for amidyl radicals; amidyl radicals containing δ,ε-unsaturation cyclized in a 5-exo fashion.
