7431-33-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7431-33-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,3 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7431-33:
(6*7)+(5*4)+(4*3)+(3*1)+(2*3)+(1*3)=86
86 % 10 = 6
So 7431-33-6 is a valid CAS Registry Number.

, (2008/06/13)

Strong acids, e.g., aluminosilicates and sulfonic acids are employed as catalysts for the (alkyl or aryl)thiolation of phenols using dialkyl or diaryl disulfides and/or (alkyl- or arylthio)phenols as thiolating agents, and for the isomerization of (alkyl- or arylthio)phenols, to prepare ortho--(alkyl- or arylthio)phenols as the predominant products.
