Check Digit Verification of cas no

The CAS Registry Mumber 149286-58-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,2,8 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 149286-58:
(8*1)+(7*4)+(6*9)+(5*2)+(4*8)+(3*6)+(2*5)+(1*8)=168
168 % 10 = 8
So 149286-58-8 is a valid CAS Registry Number.

Oxidations of benzyl and phenethyl phenyl sulfides. Implications for the mechanism of the microsomal and biomimetic oxidation of sulfides

Baciocchi, Enrico,Lanzalunga, Osvaldo,Pirozzi, Bruno

, p. 12287 - 12298 (1997)

The study of the oxidation of 4-methoxyphenethyl phenyl sulfide and 3,4-dimethoxyphenethyl phenyl sulfide with potassium 12-tungstocobalt(III)ate [Co(III)W] suggests that in the radical cations of 3,4,5-(MeO)3PhCH2SPh (4) and 2,4,6(MeO)3PhCH2SPh (5) the positive charge is not localized on the sulfur atom, but in the benzylic aromatic ring. Nevertheless, in the biomimetic and microsomal oxidation of 4 and 5 the products observed are exclusively sulfoxides and sulfones, which appears in contrast with a mechanism involving the formation of an intermediate sulfide radical cation followed by a fast oxygen rebound. A direct oxygen transfer mechanism seems most likely.
