Check Digit Verification of cas no

The CAS Registry Mumber 68193-73-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,1,9 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 68193-73:
(7*6)+(6*8)+(5*1)+(4*9)+(3*3)+(2*7)+(1*3)=157
157 % 10 = 7
So 68193-73-7 is a valid CAS Registry Number.

SYNTHESIS AND REACTIONS OF SOME TRIPLE ALKOXO- AND THIOATO-BRIDGED ARENERUTHENIUM(II) COMPLEXES. X-RAY STRUCTURE DETERMINATION OF

, p. 375 - 384 (2007/10/02)

Reaction of 2> (arene = C6H6, 1,4-MeC6H4CHMe2) with NaNH2 in CH3CN gives a dark oil which upon treatment with ROH/NaBPh4 (R = Me, Et) gives the triple bridged complexes (BPh4>.The structure of the benzene complex (R = Me) has been verified by X-ray analysis.The crystals are monoclinic, space group P21/n with a 11.725(4), b 15.573(5), c 18.739(2) Angstroem; β 103.29(2)deg.These complexes undergo reactions with tertiary phosphines and hydrogen halides.There is also spectroscopic evidence for intermolecular exchange of the bridging alkoxo ligands on mixing pure solutions of the + cations (M = Ru, Os).Reaction of 2> with Pb(SEt) 2 in CH3CN gives the analogous + cations.
