MESO-ALPHA,BETA-DI(4-PYRIDYL) GLYCOL, also known as di(4-pyridyl)glycol, is a chemical compound consisting of two pyridine rings attached to a central glycol group. It is a colorless to light yellow crystalline solid with a slightly sweet odor. MESO-ALPHA,BETA-DI(4-PYRIDYL) GLYCOL is often used as a chelating agent and is known to form stable complexes with metal ions, making it useful in various industrial and analytical applications. Additionally, it has been studied for its potential as a corrosion inhibitor and as a reagent in organic synthesis. However,
Check Digit Verification of cas no
The CAS Registry Mumber 4972-49-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,7 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4972-49:
(6*4)+(5*9)+(4*7)+(3*2)+(2*4)+(1*9)=120
120 % 10 = 0
So 4972-49-0 is a valid CAS Registry Number.

Stereospecificity in the Reductive Coupling of 4-Pyridinecarboxaldehyde
Rusling, James F.,Zuman, Petr
, p. 1906 - 1909 (1981)
One-electron reduction of 4-pyridinecarboxyaldehyde in aqueous solutions yields a mixture of dl- and meso-pinacols.Controlled-potential electrolysis (using a DME) at a potential corresponding to the limiting current of the first one-electron wave yielded dl/meso ratios of 0.57, 0.35, and 1.92 at pH values of 6.1, 10.6, and 13.3, respectively.The variation of the dl/meso ratios can be attributed to a difference in the surface orientation of radical cations (pH 6.1), uncharged radicals (pH 10.6), and radical anions (pH 13.3) that are involved in the dimerization at these different values of pH.For all dimerizations studied, voltammetric and polarographic results indicate a radical-radical coupling mechanism.
