Check Digit Verification of cas no
The CAS Registry Mumber 131-73-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131-73:
(5*1)+(4*3)+(3*1)+(2*7)+(1*3)=37
37 % 10 = 7
So 131-73-7 is a valid CAS Registry Number.

Diphenylamines containing nitro and trifluoromethylsulfonyl groups at the positions 2, 2', 4, 4', 6, and 6' were synthesized.The introduction of trifluoromethylsulfonyl groups into the diphenylamine derivatives led to a new analytical functional group.
Acid-Base Kinetics of Pyridine Studied with a Slow Spectrophotometric Indicator in Methanol

The protonation-deprotonation kinetics of pyridine in methanol has been studied by the electric field jump technique.Kinetic measurements of the electric field insensitive equilibrium B + H+ (k1) BH+ (k-1), where B denotes pyridine, were obtained by coupling the equilibrium with a field-sensitive, visibly colored indicator equilibrium.Use of the "slow" indicator 2,2',4,4',6,6'-hexanitrodiphenylamine allowed observation of the slower of the two relaxation times of the coupled system in a time range where measurements could be made with sufficient precision for a reliable extraction of the rate constants k1 and k-1 from the data.The values obtained are k1 = 1.57 +/- 0.32 * 1010 dm3mol-1s-1 and k-1 = 8.43 +/- 1.69 * 104 s-1.The value for k1 is within the expected limits for a diffusion-controlled reaction in this solvent.An ionic reaction radius of 3.9 Angstroem is calculated from the protonation rate constant value, which indicates that the neutral species involved is probably a hydrogen-bonded pyridine-methanol complex rather than free pyridine.The value for k-1 is 1 order of magnitude greater than the constant for methyl-substituted pyridines, reflecting unsubstituted pyridine's lower basicity in methanol.
