Check Digit Verification of cas no

The CAS Registry Mumber 140657-78-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,5 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 140657-78:
(8*1)+(7*4)+(6*0)+(5*6)+(4*5)+(3*7)+(2*7)+(1*8)=129
129 % 10 = 9
So 140657-78-9 is a valid CAS Registry Number.

Dinuclear complexes of platinum with the 4,4′-dipyrazolylmethane ligand. Synthesis, characterization, and X-ray crystal structure of γ-bis(4,4′-dipyrazolylmethane-N,N′)bis[dichloroplatinum(II)]- N,N-dimethylformamide (1/2) and related complexes

Broomhead, John A.,Rendina, Louis M.,Sterns, Meta

, p. 1880 - 1889 (2008/10/08)

The preparation and characterization of novel platinum complexes with the 4,4′-dipyrazolylmethane (dpzm) ligand is described. Some proposed conformational isomers of the square-planar, dinuclear platinum(II) complexes α-[Cl2Pt(μ-dpzm)2PtCl2]·0.5dmf, β-[Cl2Pt(μ-dpzm)2PtCl2], and γ-[Cl2Pt(dpzm)2PtCl2]·2dmf and the corresponding octahedral platinum(IV) complexes α-[Cl4Pt(μ-dpzm)2PtCl 4]·0.5H2O and β-[Cl4Pt(μ-dpzm)2PtCl 4]·0.5dmf·0.5H2O have been synthesized and characterized. Interconversion of the conformational forms for each oxidation state can be accomplished by various means. The mononuclear complexes cis-[PtCl2(dmf)(dpzmH)]Cl and cis-[PtCl4(dmf)(dpzmH)]Cl·0.5dmf and dinuclear mixed-oxidation state complex [Cl4Pt(μ-dpzm)2PtCl2] were also prepared and characterized. The X-ray crystal structure determination of γ-[Cl2Pt(dpzm)2PtCl2]·2dmf is reported. The complex exists as discrete molecular units with strong hydrogen-bonding to dmf solvent molecules. Each platinum atom is coordinated to two bridging dpzm ligands in a cis geometry. The crystals are monoclinic, space group P21/n, with cell parameters a = 9.790 (1) A?, b = 13.444 (2) A?, c = 12.174 (2) A?, β = 105.74 (1)°, and Z = 2. The structure was solved by the heavy-atom method and refined to R = 0.036 based on 2816 reflections.
