191226-78-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 191226-78-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,2,2 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 191226-78:
(8*1)+(7*9)+(6*1)+(5*2)+(4*2)+(3*6)+(2*7)+(1*8)=135
135 % 10 = 5
So 191226-78-5 is a valid CAS Registry Number.

15N NMR and FTIR studies of 2,4-dinitroanilines and their salts

Gierczyk,Leska,Nowak-Wydra,Schroeder,Wojciechowski,Bartl,Brzezinski

, p. 217 - 225 (2007/10/03)

Twenty-two 2,4-dinitroanilines were synthesised and their pK(a) values were determined. The 2,4-dinitroanilines and their protonated forms were studied by 15N NMR spectroscopy. The relations between the 15N NMR chemical shifts and the pK(a) values of the 2,4-dinitroanilines and their salts were found to be linear. The deprotonation reaction of N-methyl-2,4- dinitroanilines and N-methyl-2,4,6-trinitroaniline by MTBD was successful only for the latter and yielded protonated MTBD molecule and the anion in which the electrons are strongly delocalised. The kinetic parameters of the 2,4-dinitroanilines in reactions with hydroxide ions in mixed solvent DMSO:water (95:5, v/v) were determinated and discussed. (C) 2000 Elsevier Science B.V.
