Check Digit Verification of cas no

The CAS Registry Mumber 121073-89-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,0,7 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 121073-89:
(8*1)+(7*2)+(6*1)+(5*0)+(4*7)+(3*3)+(2*8)+(1*9)=90
90 % 10 = 0
So 121073-89-0 is a valid CAS Registry Number.

The Photo-CE Mechanism: the Oxidation of Tris-(p-tolyl)amine in Acetonitrile at an Illuminated Platinum Electrode

Fisher, Adrian C.,Coles, Barry A.,Compton, Richard G.,Bethell, Donald,Tripathi, Sadhana

, p. 3603 - 3606 (2007/10/02)

The oxidation of tris-(p-tolyl)amine (A) has been studied in acetonitrile solution using a channel electrode flow cell.In the dark a simple reversible one-electron oxidation to the corresponding (stable) radical cation is observed.However on irradiation with light of wavelength 300 nm a 'pre-wave' is additionally seen ca. 200 mV cathodic of the simple 'dark' process.Action spectrum measurements, preparative experiments and photocurrent/solution flow rate data are used to show that this process has the kinetic characteristics of a 'photo-CE' reaction in which the product of a photochemical pre-equilibrium involving A undergoes a dispropo rtionation reaction forming an electroactive species.The nature of the species involved is deduced and a detailed mechanistic scheme presented.Rate and equilibrium constants are estimated.The 'photo-CE' reaction is shown to have the unusual property for an electrode reaction at a channel electrode that the photocurrents decrease with solution flow rate.

Palladium Acetate-Mediated Cyclizations of Di- and Trifunctional Triarylamines, Diaryl Ethers, and Diaryl Ketones

Hellwinkel, Dieter,Kistenmacher, Thomas

, p. 945 - 950 (2007/10/02)

Triphenylamine and its 4,(4',4")-substituted nitro or ester and methyl derivatives are cyclodehydrogenated to the corresponding carbazole derivatives 4a-d with Pd(OAc)2 in acetic acid.Further cyclizations can not be observed.Multiple cyclizations of this kind, however, can be realized with compounds of the 1,4-diphenoxybenzene (6a), 1,4-dibenzoylbenzene (6b), and 2,8-diphenoxydibenzofuran type (10), where in a very simple manner benzobisbenzofurans 8a, 9a, indenofluorene-6,12-dione (8b), 11H-fluorenobenzofuran-11-one (8c), and bisbenzofurodibenzofuran (12) become accessible.
