Check Digit Verification of cas no

The CAS Registry Mumber 112213-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,2,1 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 112213-83:
(8*1)+(7*1)+(6*2)+(5*2)+(4*1)+(3*3)+(2*8)+(1*3)=69
69 % 10 = 9
So 112213-83-9 is a valid CAS Registry Number.

CH3...O Hydrogen Bond. Implications of Its Presence from the Substituent Effects on the Populations of Rotamers in 4-Substituted 9-Ethyl-1-methoxytriptycenes and 9-(Substituted Phenoxymethyl)-1,4-dimethyltriptycenes

Tamura, Yoshio,Yamamoto, Gaku,Oki, Michinori

, p. 1781 - 1788 (1987)

In the series of 4-substituted 9-ethyl-1-methoxytriptycenes, the populations of the sc conformer increase as the electron-density on the 1-methoxy-oxygen decreases.This trend was interpreted on the basis of steric repulsion which should increase as the electron density on the oxygen atom becomes high.In contrast, in the series of 9-(substituted phenoxymethyl)-1,4-dimethyltriptycenes, the high electron density on the aryloxy-oxygen favors the sc form.The stabilization of the sc form relative to the ap in the high electron density compounds in the latter series is attributed to the presence of CH3...O hydrogen bond, since other factors like Coulombic interactions, van der Waals repulsions, and van der Waals attractions could be excluded from being the main factor for the stabilization.
