Check Digit Verification of cas no

The CAS Registry Mumber 58863-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,8,6 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 58863-45:
(7*5)+(6*8)+(5*8)+(4*6)+(3*3)+(2*4)+(1*5)=169
169 % 10 = 9
So 58863-45-9 is a valid CAS Registry Number.

Aromatic Substitution. 46. Methyl (Ethyl) Thio(Dithio)carboxylation of Aromatics with S-Methyl (S-Ethyl) Thiocarboxonium and Dithiocarboxonium Fluoroantimonates

Olah, George A.,Bruce, Mark R.,Clouet, Francoise L.

, p. 438 - 442 (2007/10/02)

S-Methyl(S-ethyl)thio(dithio)carboxinium ions were prepared by reacting methyl(ethyl) fluoride-antimony pentafluoride with carbonyl sulfide (carbon disulfide) and studied with 1H and 13C NMR spectroscopy.The ions were subsequently used in the novel carboxylation reaction of arenes to S-methyl (S-ethyl) thio(dithio)benzoates.The method was also found to be adaptable to the carboxylation of polystyrene to poly(styrenecarboxylic acid) without degradation of the polymer backbone.
