91039-58-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91039-58-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,3 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91039-58:
(7*9)+(6*1)+(5*0)+(4*3)+(3*9)+(2*5)+(1*8)=126
126 % 10 = 6
So 91039-58-6 is a valid CAS Registry Number.

ANIONS OF 1,2,4-TRIAZOLES I. BASICITY WITH RESPECT TO THE HYDROGEN AND THE CARBON IN THE ANIONS OF 3-NITRO-5-R-1,2,4-TRIAZOLES

Serov, Yu. V.,Pevzner, M. S.,Kofman, T. P.,Tselinskii, I. V.

, p. 773 - 777 (2007/10/02)

The ionization constants (Ka) and equilibrium constants of hydroxymethylation (Kf) were determined for a series of 3-nitro-5-R-1,2,4-triazoles at various temperatures by spectrophotometry in aqueous buffer solutions.The thermodynamic parameters of the equilibria were calculated.The pKa values correlate by a two-parameter equation with the ?I0 and ?R0 constants of the substituents at position 5 of the triazole ring.The correlation between the log Kf values and ?I0 and ?R0 is not good.A satisfactory correlation is observed between the log Kf and pKa values, and this makes it possible to predict the position of equilibrium in the reactions of 1,2,4-triazoles with formaldehyde.
