77436-30-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77436-30-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,3 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77436-30:
(7*7)+(6*7)+(5*4)+(4*3)+(3*6)+(2*3)+(1*0)=147
147 % 10 = 7
So 77436-30-7 is a valid CAS Registry Number.

TRIFLUOROACETYLATION OF 9-METHYLCARBAZOLE. 2. PECULIARITIES OF THE REACTION DUE TO THE PRESENCE OF TRIFLUOROACETIC ACID

Moskalev, N. N.,Sirotkina, E. E.

, p. 275 - 281 (2007/10/02)

A satisfactory model of the intermediate in the formation of polyaryltrifluoromethylmethanes in the trifluoroacetylation of 9- methylcarbazole is 1,1,1-trifluoro-2,2-bis(9-methyl-3-carbazolyl)-2-hydroxyethane.The kinetic isotope effect of the reaction was evaluated.It is shown that the rate of the reaction is determined by the formation of a ? complex.The trifluoromethylation of 9-methyl-carbazole at 110 deg C is accompanied by demethylation of the substrate under the influence of trifluoroacetic acid.
