57711-75-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57711-75-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,7,1 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 57711-75:
(7*5)+(6*7)+(5*7)+(4*1)+(3*1)+(2*7)+(1*5)=138
138 % 10 = 8
So 57711-75-8 is a valid CAS Registry Number.

A novel strategy for chromogenic chemosensors highly selective toward cyanide based on its reaction with 4-(2,4-dinitrobenzylideneamino)benzenes or 2,4-dinitrostilbenes

Heying, Renata S.,Nandi, Leandro G.,Bortoluzzi, Adailton J.,Machado, Vanderlei G.

, p. 1491 - 1499 (2015/02/19)

N-(2,4-dinitrobenzylidene)-4-methoxyaniline (1), 4-(N,N-dimethylamine)-N-(2,4-dinitrobenzylidene) aniline (2), 2,4-dinitro-4′-methoxystilbene (3), and 2,4-dinitro-4′-(dimethylamino)stilbene (4) were synthesized and studied in dimethyl sulfoxide in a novel strategy as anionic chromogenic chemosensors. The color of the solutions of these compounds changed only in the presence of cyanide. The kinetic studies were performed with compounds 1-3 in an excess of cyanide. Higher second-order rate constant values were obtained for the compounds containing a methoxy group in relation to the compounds with a dimethylamino substituent, since the methoxy group donates electronic density to the 2,4-dinitrophenyl electron-accepting group less easily compared with the dimethylamino group. Stilbenes generally have greater structural rigidity than imines, facilitating the action of the substituents through the mesomeric effect. The data obtained indicate that the anion acts as a nucleophile, being responsible for C=N bond breaking. The C=C bridge is not broken in the stilbene dyes, but cyanide performs a nucleophilic attack on the 2,4-dinitrophenyl group.
