Check Digit Verification of cas no

The CAS Registry Mumber 142138-73-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,1,3 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142138-73:
(8*1)+(7*4)+(6*2)+(5*1)+(4*3)+(3*8)+(2*7)+(1*3)=106
106 % 10 = 6
So 142138-73-6 is a valid CAS Registry Number.

Study of photochemical addition of acyl radical to electron-deficient olefins

Macias,Molinillo,Massanet,Rodriguez-Luis

, p. 3345 - 3352 (1992)

The photochemical addition of acyl radical to electron-deficient olefins is studied. The scope of the reaction, the mechanism, the role that molecular oxygen plays, the influence of steric effects, and the side reaction that take place are discussed. The reaction was carried out using a range of electron-withdrawing substituents (ketones, amides, lactones, nitrile and esters) with good yields of the corresponding photoadduct in all cases.
