Check Digit Verification of cas no
The CAS Registry Mumber 4203-28-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,0 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4203-28:
(6*4)+(5*2)+(4*0)+(3*3)+(2*2)+(1*8)=55
55 % 10 = 5
So 4203-28-5 is a valid CAS Registry Number.

Kinetics and Mechanism of the Dehydrogenation of 1-Phenylsemicarbazide by Chloranil
El-Dessouky, Mohamed A.,El-Mallah, Nabila M.
, p. 1165 - 1168 (2007/10/02)
The kinetics of the oxidation of 1-phenylsemicarbazide by chloranil has been studied in ethanol and ethanol-water media.The reaction has been found to have first-order dependence in both chloranil and 1-phenylsemicarbazide and its rate increases with increasing water concentration.The energy and entropy of activation for the redox reaction have been determined.A mechanism has been proposed and the derived rate law agreed well with the experimental observations.
