Check Digit Verification of cas no

The CAS Registry Mumber 168841-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,8,8,4 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 168841-12:
(8*1)+(7*6)+(6*8)+(5*8)+(4*4)+(3*1)+(2*1)+(1*2)=161
161 % 10 = 1
So 168841-12-1 is a valid CAS Registry Number.

Stereochemical nonrigidity in metallocenium ions

Siedle, A. R.,Newmark, R. A.

, p. 119 - 126 (2007/10/02)

Dynamic NMr spectrscopy of the MeB(C6F5)3- salts of a series of ring-substituted zirconium- and hafnium-containing metallocenium ions, exemplified by (RCp)2ZrCH3+, reveals two exchange processes.One, having the lower free energy of activation, involves shift of the CH3 group from one lateral equatorial orbital to the other.The second results from exchange between the metal-CH3 and B-CH3 groups.Effects of structural variations on exchange barriers are discussed and related to metallocenium ion-catalyzed olefin polymerization.Keywords: Metallocenium ions; Stereochemical nonrigidity; Zirconium; Hafnium
