Check Digit Verification of cas no
The CAS Registry Mumber 143924-44-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,9,2 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 143924-44:
(8*1)+(7*4)+(6*3)+(5*9)+(4*2)+(3*4)+(2*4)+(1*4)=131
131 % 10 = 1
So 143924-44-1 is a valid CAS Registry Number.

Preparation of Piperidinylpyridines via Selective Reduction of Bipyridines with Nickel-Aluminum Alloy
Lunn, George
, p. 6317 - 6320 (1992)
Bipyridines were reduced to piperidinylpyridines in modest yield using nickel-aluminum alloy in potassium hydroxide solution.The reduction was selective, and 3-substituted rings were reduced in preference to 4-substitution.Thus 2,3-bipyridine gave only 2-(3'-piperidinyl)pyridine, 2,4-bipyridine gave only 2-(4'-piperidinyl)pyridine, and 3,4-bipyridine gave only 4-(3'-piperidinyl)pyridine.The symmetrical 2,2'- and 4,4'-bipyridines also gave the corresponding piperidinylpyridines, but the reduction of 3,3'-bipyridine was too sluggish to be practical.The products were identified using 13C NMR spectroscopy, and the 13C NMR spectra of the starting bipyridines were also recorded.
