Check Digit Verification of cas no

The CAS Registry Mumber 134889-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,8 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134889-87:
(8*1)+(7*3)+(6*4)+(5*8)+(4*8)+(3*9)+(2*8)+(1*7)=175
175 % 10 = 5
So 134889-87-5 is a valid CAS Registry Number.

Activation of Carbon Dioxide: Nickel-Catalyzed Electrochemical Carboxylation if Diynes

Derien, Sylvie,Clinet, Jean-Claude,Dunach, Elisabet,Perichon, Jacques

, p. 2578 - 2588 (2007/10/02)

The simualtaneous activation of carbon dioxide and diynes by electrogenerated LNi(0) complexes (L=bpy, pentamethyldiethylenetriamine: PMDTA) enables the selective incorporation of one molecule of CO2 into the unsaturated systems and the preparative-scale

First Example of Direct Carbon Dioxide Incorporation into 1,3-Diynes: A Highly Regio- and Stereo-selective Nickel-catalysed Electrochemical Reaction

Derien, Sylvie,Clinet, Jean-Claude,Dunach, Elisabet,Perichon, Jacques

, p. 549 - 550 (2007/10/02)

The electrosynthesis of 2-vinylidene-3-yne carboxylic acids from carbon dioxide and substituted 1,3-diynes is catalysed by a nickel-triamine complex and results in a regio- and stereo-selective addition to one triple bond.
