Check Digit Verification of cas no

The CAS Registry Mumber 121114-62-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,1,1 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 121114-62:
(8*1)+(7*2)+(6*1)+(5*1)+(4*1)+(3*4)+(2*6)+(1*2)=63
63 % 10 = 3
So 121114-62-3 is a valid CAS Registry Number.

Dynamic NMR as a Nondestructive Method for the Determination of Rates of Dissociation. XV. Dissociation of Thioether and Ether hment from Ammonigands in Tin(IV) and Boron Complexes and Significance of Entropy of Activation Therein

Oki, Michinori,Yamada, Yasuhisa

, p. 1191 - 1194 (2007/10/02)

The rates of dissociation of thioether ligands which are imbedded in organotin(IV) compounds, such as trichlorostannane, were determined by the dynamic NMR method.The dynamic processes of the corresponding ether ligands was too fast to detect as the change in line shapes in 1H NMR spectra.All the boron compounds examined, which possessed similar structures to the stannane and were of the boronate type, failed to show dissociation of a thioether or ether ligand due to their large rates of dissociation.The rates of dissociation of a thioether-tribromoboron complex were determined by the same technique.The feature of the activation parameters was that the compounds examined exhibited fairly large positive entropy of activation in accordance with other results that involve dissociation of ionic species into covalent species.
