Check Digit Verification of cas no
The CAS Registry Mumber 68575-36-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,5,7 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 68575-36:
(7*6)+(6*8)+(5*5)+(4*7)+(3*5)+(2*3)+(1*6)=170
170 % 10 = 0
So 68575-36-0 is a valid CAS Registry Number.

Process for preparing 3,5-dichloro-α-methylstyrene
-
, (2008/06/13)
In the preparation of 3,5-dichloro-α-methylstyrene by isopropylation of an m/p-dichlorobenzene mixture, isomerization of the resulting alkylation mixture, subsequent side chain bromination of the alkylation mixture and dehydrobromination of the resulting bromination mixture, the improvement which comprises reacting an excess of an m/p-dichlorobenzene mixture which contains at least 50% by weight of m-dichlorobenzene with isopropyl halide, isomerizing the resulting alkylation mixture under pressure in the presence of aluminum chloride until thermodynamic equilibrium has been attained, separating off the isomerized alkylation mixture from the unreacted m/p-dichlorobenzene mixture, and recycling the unreacted mixture for further reaction.
