Check Digit Verification of cas no

The CAS Registry Mumber 87241-33-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,4 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87241-33:
(7*8)+(6*7)+(5*2)+(4*4)+(3*1)+(2*3)+(1*3)=136
136 % 10 = 6
So 87241-33-6 is a valid CAS Registry Number.

Preparation of 2,5-dichlorophenol

-

, (2008/06/13)

2,5-Dichlorophenol is readily and facilely prepared from 2,5-dichloro-4-hydroxybenzenesulfonic acid or salt thereof, said sulfonic acid/sulfonate itself being characteristically produced by hydrolysis of a precursor trichlorobenzenesulfonic acid, by cleaving the sulfo/sulfonate moiety therefrom by treatment, e.g., under reflux, with a constant boiling point hydrobromic acid.
