Check Digit Verification of cas no

The CAS Registry Mumber 104049-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,0,4 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 104049-33:
(8*1)+(7*0)+(6*4)+(5*0)+(4*4)+(3*9)+(2*3)+(1*3)=84
84 % 10 = 4
So 104049-33-4 is a valid CAS Registry Number.

REDUCTION ELECTROCHIMIQUE DES DERIVES CARBONYLES INSATURES IX. INDANONES ET TETRALONES: ELECTROLYSES MIXTES EN PRESENCE D'ELECTROPHILES

Moing, Armelle Orliac-Le,Delaunay, Jacques,Lebouc, Alain,Simonet, Jacques

, p. 4483 - 4494 (1985)

It is shown that activated cyclic carbonyl compounds, such as tetralones and indanones, can behave in a particular manner when they are reduced in presence of electrophiles.Two classes of electrophiles were chosen: alkyl halides and carbon dioxide.The reactivity (alkylation and carboxylation) often depends on the nature of the activated ketone used as a substrate.
