Check Digit Verification of cas no

The CAS Registry Mumber 112537-93-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,5,3 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 112537-93:
(8*1)+(7*1)+(6*2)+(5*5)+(4*3)+(3*7)+(2*9)+(1*3)=106
106 % 10 = 6
So 112537-93-6 is a valid CAS Registry Number.

The Rotation-dominated Ring Inversion/Nitrogen Inversion/Rotation Process in N-Acyloxy-2,2,6,6-tetramethylpiperidines. A Dynamic NMR Study

Anderson, J. Edgar,Corrie, John E. T.

, p. 1027 - 1031 (2007/10/02)

The temperature dependence of the NMR spectra of a series of N-acyloxy-2,2,6,6-tetramethylpiperidines is reported and discussed in terms of a conformational process which involves ring inversion, nitrogen inversion and rotation about the nitrogen-oxygen bond.Nitrogen inversion contributes ca. 11 kcal mol-1 to the observed barriers, so in the compounds with higher barriers, steric interaction of the acyl and methyl groups during rotation determines the barrier height.
