Check Digit Verification of cas no
The CAS Registry Mumber 67832-11-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,8,3 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 67832-11:
(7*6)+(6*7)+(5*8)+(4*3)+(3*2)+(2*1)+(1*1)=145
145 % 10 = 5
So 67832-11-5 is a valid CAS Registry Number.

Kinetics of oxidative ammonolysis of 4-bromo-o-xylene: V. Synthesis of 4-bromophthalonitrile
Bagirzade,Tagiev
, p. 1085 - 1090 (2014/08/05)
Oxidative ammonolysis of 4-bromo-o-xylene on a V-Sb-Bi-Zr/γ-Al 2O3 catalyst gives 74.82 mol % of 4-bromophthalonitrile at a high conversion of the starting xylene in a one-cycle process. The process with recirculation results in decreased number of by-products and contribution of deep oxidation and increased selectivity in 4-bromophthalonitrile up to 95.42-96.58%.
