1724-08-9 Usage
General Description
2,3-Norbornanedicarboxylic Acid, also known as Cyclic-2.3.-(1,2:3,4-diepoxybutane)-1,4.5.6-tetrahydrophthalic acid or endo-cis-5-Norbornene-endo-2,3-dicarboxylic acid, is an organic compound and a dicarboxylic acid with the molecular formula C9H10O4. This technical-grade chemical appears as white crystals and has a mild odour. It is used as a reagent in organic synthesis, particularly in the preparation of certain polymers. With an estimated melting point of 165-167 °C, it has potential hazards such as the generation of toxic gases or vapours when heated. Therefore, protective measures are advised when handling it.
Check Digit Verification of cas no
The CAS Registry Mumber 1724-08-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,2 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1724-08:
(6*1)+(5*7)+(4*2)+(3*4)+(2*0)+(1*8)=69
69 % 10 = 9
So 1724-08-9 is a valid CAS Registry Number.

Electrochemical incorporation of carbon dioxide into alkenes by nickel complexes
Derien, Sylvie,Clinet, Jean-Claude,Dunach, Elisabet,Perichon, Jacques
, p. 5235 - 5248 (2007/10/02)
Electrogenerated Ni(0) complexes from stable Ni(II) compounds are the catalysts for the electrochemical incorporation of carbon dioxide into carbon-carbon double bonds. Different kind of olefin derivatives have been carboxylated to afford mono- or dicarboxylic acid derivatives depending on the alkene structure. The electrolyses are carried out in one compartment cells fitted with a magnesium anode under mild conditions.
