General Description
[4,4'-BIPYRIDINE]-2,2',6,6'-TETRACARBOXYLIC ACID TETRAETHYL ESTER, also known as tetrakis(ethoxycarbonyl) 4,4'-bipyridine-2,2',6,6'-tetracarboxylate, is an organic chemical with the molecular formula C34H38N2O12. It is a tetraethyl ester derivative of 4,4'-bipyridine-2,2',6,6'-tetracarboxylic acid. This chemical is often used in coordination chemistry and materials science as a ligand for metal ions and in the synthesis of metal-organic frameworks. It has also been studied for potential applications in pharmaceuticals and optoelectronic devices.
Check Digit Verification of cas no
The CAS Registry Mumber 124558-63-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,5,5 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 124558-63:
(8*1)+(7*2)+(6*4)+(5*5)+(4*5)+(3*8)+(2*6)+(1*3)=130
130 % 10 = 0
So 124558-63-0 is a valid CAS Registry Number.

A Convenient Synthesis of 2,2',6,6'-Tetramethyl-4,4'-bipyridine and Its Oxidation to 2,2',6,6'-Tetracarboxy-4,4'-bipyridine
Huenig, Siegfried,Wehner, Ingeborg
, p. 552 - 554 (2007/10/02)
By reaction of 2,6-dimethylpyridine (1b) with sodium the tetrahydro-4,4'-bipyridine bis-sodium salt 2b is formed.Of different dehydrogenation reagents tested, only sulfur dioxide affords the title compound 3b, in 49percent overall yield.By oxidation of 3b with chromium trioxide, 2,2',6,6'-tetracarboxy-4,4'-bipyridine (3c, 70percent) is produced, a valuable precursor for several 2,2',6,6'-tetrasubstituted 4,4'-bipyridines, e.g., the corresponding acid chloride 3d and the carboxylic esters 3e and 3f.
