Check Digit Verification of cas no

The CAS Registry Mumber 29181-50-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,1,8 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 29181-50:
118 % 10 = 8
So 29181-50-8 is a valid CAS Registry Number.

C?H Cyanation of 6-Ring N-Containing Heteroaromatics

Elbert, Bryony L.,Farley, Alistair J. M.,Gorman, Timothy W.,Johnson, Tarn C.,Genicot, Christophe,Lallemand, Bénédicte,Pasau, Patrick,Flasz, Jakub,Castro, José L.,MacCoss, Malcolm,Paton, Robert S.,Schofield, Christopher J.,Smith, Martin D.,Willis, Michael C.,Dixon, Darren J.

Heteroaromatic nitriles are important compounds in drug discovery, both for their prevalence in the clinic and due to the diverse range of transformations they can undergo. As such, efficient and reliable methods to access them have the potential for far-reaching impact across synthetic chemistry and the biomedical sciences. Herein, we report an approach to heteroaromatic C?H cyanation through triflic anhydride activation, nucleophilic addition of cyanide, followed by elimination of trifluoromethanesulfinate to regenerate the cyanated heteroaromatic ring. This one-pot protocol is simple to perform, is applicable to a broad range of decorated 6-ring N-containing heterocycles, and has been shown to be suitable for late-stage functionalization of complex drug-like architectures.

Mild and general methods for the palladium-catalyzed cyanation of aryl and heteroaryl chlorides

Littke, Adam,Soumeillant, Maxime,Kaltenbach III, Robert F.,Cherney, Robert J.,Tarby, Christine M.,Kiau, Susanne

, p. 1711 - 1714 (2008/02/02)

New methods for the palladium-catalyzed cyanation of aryl and heteroaryl chlorides have been developed, featuring sterically demanding, electron-rich phosphines. Highly challenging electron-rich aryl chlorides, in addition to electron-neutral and electron-deficient substrates, as well as nitrogen- and sulfur-containing heteroaryl chlorides can all undergo efficient cyanation under relatively mild conditions using readily available materials. In terms of substrate scope and temperature, these methods compare very favorably with the state-of-the-art cyanations of aryl chlorides.

An Electron Spin Resonance and Voltametric Investigation of Some 2-Mono- and 2,4-Di-substitued Pyridinyl Radicals

Greci, Lucedio,Alberti, Angelo,Carelli, Italo,Trazza, Antonio,Casini, Antonio

, p. 2013 - 2018 (2007/10/02)

The chemical reduction of some 2-monosubstitued and 2,4-disubstitued pyridinium ions has been investigated by means of e.s.r. spectroscopy and the result compared with those of an electrochemical study on the same species.By combining the electrochemical and e.s.r. data, a scale of stability has been determined for the investigated pyridinyl radicals.N-Methyl-2-cyanopyridinyl, wich was found to be too unstable to be observed, eventually evolved to the 2,4-dicyano-substitued radical.E.s.r. studies have also been carried out on the structurally similar, although more persistent, N-germylpyridinyls.
