Check Digit Verification of cas no
The CAS Registry Mumber 148705-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,7,0 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 148705-34:
(8*1)+(7*4)+(6*8)+(5*7)+(4*0)+(3*5)+(2*3)+(1*4)=144
144 % 10 = 4
So 148705-34-4 is a valid CAS Registry Number.

Selectivity in the thermal cyclization of 2-piperidino-3-vinylpyridines
Ojea,Maestro,Quintela
, p. 2691 - 2700 (2007/10/02)
New achiral 2-(4-substituted-piperidino)-3-vinylpyridines undergo stereoselective isomerization to pyrido [1,2-a][1,8]naphthyridines. The stereoselectivity of this reaction was found dependent on the experimental conditions (temperature and solvent polari
