Check Digit Verification of cas no

The CAS Registry Mumber 12125-80-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,2 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 12125-80:
(7*1)+(6*2)+(5*1)+(4*2)+(3*5)+(2*8)+(1*0)=63
63 % 10 = 3
So 12125-80-3 is a valid CAS Registry Number.

ferrocenium (cas 12125-80-3) strong adsorption on sulfonated polyaniline modified electrodes07/30/2019

The electrocatalytic oxidation of ferrocene (Fc) at neutral pH in aqueous solution has been studied over thin films of electroactive sulfonated polyaniline (SPAN) by cyclic voltammetry. Strong adsorption of the oxidised species (ferrocenium ion) on the polymer arises as the explanation for the n...detailed

Proton-coupled oxygen reduction at liquid-liquid interfaces catalyzed by cobalt porphine

Hatay, Imren,Su, Bin,Li, Fei,Mendez, Manuel Alejandro,Khoury, Tony,Gros, Claude P.,Barbe, Jean-Michel,Ersoz, Mustafa,Samec, Zdenek,Girault, Hubert H.

, p. 13453 - 13459 (2009)

Cobalt porphine (CoP) dissolved in the organic phase of a biphasic system is used to catalyze O2 reduction by an electron donor, ferrocene (Fc). Using voltammetry at the interface between two immiscible electrolyte solutions (ITIES), it is poss

Evidence for a Single-Electron-Transfer Activation in the Cleavage of Cobalt-Carbon Bonds of Alkylcobalt(III) Complexes with Iodine

Fukuzumi, Shunichi,Ishikawa, Kunio,Tanaka, Toshio

, p. 1801 - 1804 (1986)

Evidence for a single-electron-transfer (SET) activation in the cleavage of cobalt-carbon bonds of alkylcobalt(III) complexes with iodine is shown by the identification of products that could arise only via an SET pathway as well as by the kinetic comparison between the cleavage reaction of alkylcobalt(III) complexes with iodine and the electron-transfer reaction of ferrocene derivatives with iodine in acetonitrile.

Mechanism of four-electron reduction of dioxygen to water by ferrocene derivatives in the presence of perchloric acid in benzonitrile, catalyzed by cofacial dicobalt porphyrins

Fukuzumi, Shunichi,Okamoto, Ken,Gros, Claude P.,Guilard, Roger

, p. 10441 - 10449 (2004)

The selective two-electron reduction of dioxygen occurs in the case of a monocobalt porphyrin [Co(OEP)], whereas the selective four-electron reduction of dioxygen occurs in the case of a cofacial dicobalt porphyrin [Co 2(DPX)]. The other cofacial dicobalt porphyrins [Co2(DPA), Co2(DPB), and Co2(DPD)] also catalyze the two-electron reduction of dioxygen, but the four-electron reduction is not as efficient as in the case of Co2(DPX). The μ-superoxo species of cofacial dicobalt porphyrins were produced by the reactions of cofacial dicobalt(II) porphyrins with dioxygen in the presence of a bulky base and the subsequent one-electron oxidation of the resulting μ-peroxo species by iodine. The superhyperfine structure due to two equivalent cobalt nuclei was observed at room temperature in the ESR spectra of the μ-superoxo species. The superhyperfine coupling constant of the μ-superoxo species of Co2(DPX) is the largest among those of cofacial dicobalt porphyrins. This indicates that the efficient catalysis by Co2(DPX) for the four-electron reduction of dioxygen by Fe(C5H4Me)2 results from the strong binding of the reduced oxygen with Co2(DPX) which has a subtle distance between two cobalt nuclei for the oxygen binding. Mechanisms of the catalytic two-electron and four-electron reduction of dioxygen by ferrocene derivatives will be discussed on the basis of detailed kinetics studies on the overall catalytic reactions as well as on each redox reaction in the catalytic cycle. The turnover-determining step in the Co(OEP)-catalyzed two-electron reduction of dioxygen is an electron transfer from ferrocene derivatives to Co(OEP) +, whereas the turnover-determining step in the Co 2(DPX)-catalyzed four-electron reduction of dioxygen changes from the electron transfer to the O-O bond cleavage of the peroxo species of Co 2(DPX), depending on the electron donor ability of ferrocene derivatives.

Dinitrogen addition to c-C5H5Fe(+), C6H6Fe(+) and FeO(+) in the gas phase

Baranov, Vladimir I.,Javahery, Glolamreza,Bohme, Diethard K.

, p. 339 - 343 (1995)

Results of an experimental study using the selection-ion flow tube technique are reported for reactions of bare Fe(+) and iron containing FeX(+) cations (X=C6H6 (or B), c-C5H5 (or Cp), O, (Cp)2, B2) with dinitrogen at 294+/-3 K and at a helium buffer-gas pressure of 0.35+/-0.01 Torr. Fe(+), B2Fe(+) and Cp2Fe(+) do not react with dinitrogen. A very slow sequential addition of two N2 molecules was observed with FeO(+). CpFe(+) and BFe(+) reacted without the subsequent addition of a second N2 molecule. These results provide insight into the bonding of N2 as a ligand with Fe as the coordination centre in the gas-phase, and into intrinsic kinetic aspects of dinitrogen addition.
