Check Digit Verification of cas no
The CAS Registry Mumber 4986-05-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,8 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4986-05:
(6*4)+(5*9)+(4*8)+(3*6)+(2*0)+(1*5)=124
124 % 10 = 4
So 4986-05-4 is a valid CAS Registry Number.

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
