Check Digit Verification of cas no
The CAS Registry Mumber 194800-56-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,8,0 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 194800-56:
(8*1)+(7*9)+(6*4)+(5*8)+(4*0)+(3*0)+(2*5)+(1*6)=151
151 % 10 = 1
So 194800-56-1 is a valid CAS Registry Number.

Varying the electronic structure of surface-bound ruthenium(II) polypyridyl complexes

In the design of light-harvesting chromophores for use in dye-sensitized photoelectrosynthesis cells (DSPECs), surface binding to metal oxides in aqueous solutions is often inhibited by synthetic difficulties. We report here a systematic synthesis approach for preparing a family of Ru(II) polypyridyl complexes of the type [Ru(4,4′-R2-bpy)2(4,4′-(PO3H2)2-bpy)]2+ (4,4′(PO3H2)2-bpy = [2,2′-bipyridine]-4,4′-diylbis(phosphonic acid); 4,4′-R2-bpy = 4,4′-R2-2,2′-bipyridine; and R = OCH3, CH3, H, or Br). In this series, the nature of the 4,4′-R2-bpy ligand is modified through the incorporation of electron-donating (R = OCH3 or CH3) or electron-withdrawing (R = Br) functionalities to tune redox potentials and excited-state energies. Electrochemical measurements show that the ground-state potentials, E′(Ru3+/2+), vary from 1.08 to 1.45 V (vs NHE) when the complexes are immobilized on TiO2 electrodes in aqueous HClO4 (0.1 M) as a result of increased Ru dπ-π back-bonding caused by the lowering of the π orbitals on the 4,4′-R2-bpy ligand. The same ligand variations cause a negligible shift in the metal-to-ligand charge-transfer absorption energies. Emission energies decrease from max = 644 to 708 nm across the series. Excited-state redox potentials are derived from single-mode Franck-Condon analyses of room-temperature emission spectra and are discussed in the context of DSPEC applications.
