Check Digit Verification of cas no

The CAS Registry Mumber 77289-31-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,8 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77289-31:
(7*7)+(6*7)+(5*2)+(4*8)+(3*9)+(2*3)+(1*1)=167
167 % 10 = 7
So 77289-31-7 is a valid CAS Registry Number.

Electron Spin Resonance Spectra of Dibromo- and Dichloro-complexes of Vanadium(IV)

Jezierski, Adam,Raynor, Barrie

, p. 1 - 7 (2007/10/02)

Reactions of SOCl2 or SOBr2 with a range of 20 vanadyl complexes, (L4= quadridentate or two bidentate ligands), yield solutions containing cis- or trans-dihalogen vanadium(IV) complexes . They are characterised by their e.s.r.spectra and in most cases the unpaired electron is in a dx2- y2 orbital.In some cases both cis and trans isomers can be detected and characterised, because of significant differnces in e.s.r. parameters.In the cas of , the unpaired electron is in a dz2 orbital and the structure is thought to be trigonal prismatic.
