Check Digit Verification of cas no
The CAS Registry Mumber 72630-78-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,6,3 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 72630-78:
(7*7)+(6*2)+(5*6)+(4*3)+(3*0)+(2*7)+(1*8)=125
125 % 10 = 5
So 72630-78-5 is a valid CAS Registry Number.

A study of the kinetics and mechanism of the fluorination of 2,4,5-trichloro-6-methylpyriimidie (TCMP) to form 2,4-difluoro-5-chloro-6-methylpyrimidine (DFCMP) in polar aprotic solvents with KF or NaF has been performed.The rate constants of the fluorination under various conditions were measured.This fluorination proceeds as a pseudo-first-order consecutive reaction.The values of the activation enthalpy ΔH*, the activation entropy ΔS* and Arrhenius activation energy ΔEa were evaluated and the influence of solvents, catalysts and fluorinating agents was discussed.The CNDO/2 method has been applied to the calculation of the reaction path of the fluorination and the energy levels of the components.The calculated results agree well with experimental observation.

Selective chlorine/fluorine exchange reactions on tetrachloropyrimidine, 6-methyl-, 6-chloromethyl-, 6-dichloromethyl, and 6-trichloromethyl-2,4,5-trichloropyrimidine are described.Sodium fluoride, potassium fluoride, hydrogen fluoride, and antimony trifluoride were used as the fluorinating agents.It was found that NaF and KF fluorinate only in the heterocyclic nucleus, HF in the nucleus and in the chlorinated methyl group, and SbF3 only in the chlorinated methyl group.In the first stage of fluorination with NaF only chlorine bound in position 4 of the pyrimidine ring is exchanged.The HF reaction is an equilibrium reaction in which the substitution of the fluorine for the first chlorine atom occurs preferentially in position 2.The behaviour of partly fluorinated pyrimidines in nucleophilic exchange reactions is also discussed.
