Check Digit Verification of cas no

The CAS Registry Mumber 204653-23-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,6,5 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 204653-23:
(8*2)+(7*0)+(6*4)+(5*6)+(4*5)+(3*3)+(2*2)+(1*3)=106
106 % 10 = 6
So 204653-23-6 is a valid CAS Registry Number.

PGSE diffusion NMR studies on mononuclear and dinuclear cationic platinum salts of (S)-MeO-Biphep and (R)-p-tolyl-BINAP

Schott, Danièle,Pregosin, Paul S.,Albinati, Alberto,Rizzato, Silvia

, p. 3203 - 3212 (2007)

PGSE diffusion NMR studies on a series of mononuclear and dinuclear cationic platinum salts derived from (S)-MeO-Biphep and (R)-p-tolyl-BINAP are reported. The data show that (a) one can readily distinguish between mononuclear and dinuclear cations (b) the amount of ion pairing can be estimated qualitatively and (c) the charge delocalization rather than the amount of formal charge per metal cation is important for the position of the anion. The solid-state structure of the chloro-bridged salt, [Pt(μ-Cl){(S)-MeO-Biphep}]2(CF3SO3)2, is reported.
