Check Digit Verification of cas no
The CAS Registry Mumber 666-15-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 666-15:
(5*6)+(4*6)+(3*6)+(2*1)+(1*5)=79
79 % 10 = 9
So 666-15-9 is a valid CAS Registry Number.

Unsensitized photooxidation of sulfur compounds with molecular oxygen in solution
Robert-Banchereau, Evelyne,Lacombe, Sylvie,Ollivier, Jean
, p. 2087 - 2102 (2007/10/03)
The short wavelength irradiation of aliphatic disulfides, sulfides and of n-butanethiol in alcohols or aqueous acetonitrile in the presence of oxygen was investigated: the corresponding sulfonic acids are produced in good yields for short alkyl chain compounds, together with smaller amounts of sulfuric and carboxylic acids. In acetonitrile, the influence of added water on the reaction course is evidenced: increased reaction rate and acid yields, control of sulfuric acid formation. Intermediates such as sulfinic acid and thiosulfonate were detected and their rates of formation were monitored. The reaction appears to involve thiyl radicals giving rise to sulfonyl radicals in the presence of oxygen. A first tentative hypothesis concerning the mechanism is advanced.
