Check Digit Verification of cas no
The CAS Registry Mumber 62697-73-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,6,9 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 62697-73:
(7*6)+(6*2)+(5*6)+(4*9)+(3*7)+(2*7)+(1*3)=158
158 % 10 = 8
So 62697-73-8 is a valid CAS Registry Number.

Tetrabromoaurate(III) is an efficient catalyst for the oxidation of sulfides to sulfoxides by nitric acid in a biphasic system (nitromethane/water).The system is selective and can be applied to the oxidation of any type of dialkyl and alkyl aryl sulfide and also of diaryl sulfides activated by electron-releasing substituents.The nature of the active species has been investigated in relation to the mechanistic aspects.
