33642-01-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 33642-01-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,4 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 33642-01:
(7*3)+(6*3)+(5*6)+(4*4)+(3*2)+(2*0)+(1*1)=92
92 % 10 = 2
So 33642-01-2 is a valid CAS Registry Number.

Oxidation of Iodo- and Bromo-Substituted Polymethylbenzenes in the System PbO2–CF3COOH–CH2Cl2
Sandzhieva,Aryamova,Sukharzhevskii,Grinenko,Vasilyev
, (2018)
The oxidation of mono- and diiodo- and -bromo-substituted polymethylbenzenes (mesitylene and durene) in the system PbO2–CF3COOH–CH2Cl2 at room temperature (2–70 h) leads mainly to the formation of iodo- and brom
