Check Digit Verification of cas no
The CAS Registry Mumber 51905-34-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,9,0 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 51905-34:
(7*5)+(6*1)+(5*9)+(4*0)+(3*5)+(2*3)+(1*4)=111
111 % 10 = 1
So 51905-34-1 is a valid CAS Registry Number.

SYNTHESIS, STRUCTURES, AND REACTIVITIES OF SOME PENTAMETHYLCYCLOPENTADIENYL-SULPHUR COMPOUNDS
Bard, Allen J.,Cowley, Alan H.,Leland, Jonathan K.,Thomas, Gillian J. N.,Norman, Nicholas C.,et al.

The pentamethylcyclopentadienyl-sulphur compounds S(C5Me5)2 (1) and S2(C5Me5)2 (2) have been prepared by the reaction of Li(C5Me5) with SCl2 and S2Cl2, respectively.Compounds (1) and (2) were characterised by n.m.r. and mass spectroscopy.The X-ray crystal structure of (1) has been determined.Compound (1) crystallises in the monoclinic space group P21/c (no. 14), with a = 10.375(2), b = 11.274(2), c = 16.132(9) Angstroem, β = 91.92(3) deg, and Z = 4.The reaction of (1) with results in the known cluster compound, (3), the identy of which was confirmed by X-ray crystallography.Unsuccessful attempts were made to prepare cations of the type n+ by (i) oxidation of (1) and (2), or (ii) the reaction of S(C5Me5)Cl (Prepared in situ) with Al2Cl6.Cyclic voltammetric experiments on (1) and C5Me5H suggest that oxidation occurs at the carbocyclic ring rather than at the sulphur atom.
