Check Digit Verification of cas no

The CAS Registry Mumber 111399-31-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,3,9 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 111399-31:
(8*1)+(7*1)+(6*1)+(5*3)+(4*9)+(3*9)+(2*3)+(1*1)=106
106 % 10 = 6
So 111399-31-6 is a valid CAS Registry Number.

Kinetic and equilibrium study of the ring opening of 2-aryl-1-methyl-1-pyrrolinium ions in aqueous solution

McClelland, Robert A.,Seaman, N. Esther

, p. 1689 - 1694 (2007/10/02)

Ultraviolet spectral and kinetic measurements are reported for the transformations in aqueous solution undergone by the cyclic iminium ion, the 2-aryl-1-methyl-1-pyrrolinium ion I+.In solutions with pH 9.5 this ion equilibrates with a ring-op
