1057401-28-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1057401-28-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,7,4,0 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1057401-28:
(9*1)+(8*0)+(7*5)+(6*7)+(5*4)+(4*0)+(3*1)+(2*2)+(1*8)=121
121 % 10 = 1
So 1057401-28-1 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
