2683-68-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2683-68-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,8 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2683-68:
(6*2)+(5*6)+(4*8)+(3*3)+(2*6)+(1*8)=103
103 % 10 = 3
So 2683-68-3 is a valid CAS Registry Number.

Acetyl exchange between pyridine N-oxides in acetonitrile solutions: An attempt to apply the Marcus equation to acetyl transfer

Rybachenko,Schroeder,Chotii,Titov,Kovalenko,Leska,Grebenyuk

, p. 1608 - 1615 (2001)

Forty-three (including eight identical) reactions of acetyl transfer from N-acetyloxypyridinium salts to pyridine N-oxides in acetonitrile solutions were studied. The rate constants k2 vary in the range 107-10-1 1 mol-1 s-1; the equilibrium constants K, in the range 107-10-7; the activation enthalpy ΔH≠, in the range 17-30 kJ mol-1; the activation entropy -ΔS≠, in the range 60-85 J mol-1 K-1; and the heat of reaction -ΔH0, within ±50 kJ mol-1. All reactions occur in a single stage by the concerted SN2 mechanism with a low degree of bond cleavage in the transition state. The rate and equilibrium of the acetyl exchange are satisfactorily described by the Bronsted equation. The quality of predicting the reactivity is substantially improved by introducing into the correlation equation a second parameter, the rates of identical reactions.

Equilibrium of acyl transfer between pyridine N-oxides and their acylonium salts

Rubachenko,Schroeder,Chotii,Kovalenko,Red'ko,Lenska

, p. 1241 - 1246 (2008/12/22)

Transfer of acyl groups from N-acyloxypyridinium salts to pyridine N-oxides in acetonitrile was studied. The equilibrium constants of acyl exchange were determined. These quantities vary in the range covering eight orders of magnitude, depending on the st

Rate and Equilibrium Constants of Dimethylcarbamoyl Transfer between Pyridine N-Oxides

Schroeder,Rybachenko,Chotii,Kovalenko,Grebenyuk,Lenska,Eitner

, p. 455 - 462 (2007/10/03)

Dimethylcarbamoyl transfer from N-acyloxypyridinium salts to pyridine N-oxides in acetonitrile occurs in one stage by the forced concerted SN2 mechanism. The rate and equilibrium of the reaction are fairly described by the Bronsted equation. The Marcus equation provides a much higher quality of reactivity predictions.

Equilibrium of acetyl transfer between pyridine N-Oxides and their acetylonium salts

Rybachenko,Chotii,Kovalenko,Schroeder

, p. 786 - 788 (2007/10/03)

The equilibrium constants of acetyl transfer between O-acetylonium salts of a series of pyridine N-oxides and 4-(4-dimethylaminostyryl)pyridine N-oxide in acetonitrile and methylene chloride were determined. The equilibrium constants correlate with the ac
