Check Digit Verification of cas no

The CAS Registry Mumber 218945-04-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,9,4 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 218945-04:
(8*2)+(7*1)+(6*8)+(5*9)+(4*4)+(3*5)+(2*0)+(1*4)=151
151 % 10 = 1
So 218945-04-1 is a valid CAS Registry Number.

Oxidation reactions of azines. 10. Synthesis, structure, and oxodihydroxylation of 3-hydroxymethyl-1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine

Soldatenkov,Temesgen,Polyanskii,Soldatova,Kolyadina,Golovtsov,Sergeeva

, p. 471 - 477 (2007/10/03)

It has been established that oxidation of a mixture of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine and dicyanomethane or formaldehyde with manganese dioxide gives 3-hydroxymethyl-1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine, the structure of which was confirmed by X-ray structural analysis. Some oxidative conversions by potassium permanganate of the product formed and its esters have been studied. These included lactamization, aromatization, and oxodihydroxylation.
