Check Digit Verification of cas no
The CAS Registry Mumber 28749-00-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,7,4 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28749-00:
(7*2)+(6*8)+(5*7)+(4*4)+(3*9)+(2*0)+(1*0)=140
140 % 10 = 0
So 28749-00-0 is a valid CAS Registry Number.

A New Synthesis for 1,2,4-Triazolo[1,5-a]-pyridines and 1,2,4-Triazolo[1,5-a]isoquinolines

Condensation of cyano acid hydrazide 1 with cyclopentanone in refluxing ethanolic piperidine yields hydrazone 2. With mixtures of aliphatic aldehydes and different active methylene reagents, 2 reacts to 1,2,4-triazolo[1,5-a]pyridines (8a-f). Compound 2 also reacts with arylidenes 9a-g to give triazolopyridines 10a-g. Reaction of 2 with aromatic aldehydes affords compounds 13a-c. Diazotation of 2 with aryldiazonium chloride in ethanol at 0°C leads to the azo adducts 15a-d. The thieno-1,2,4-triazolopyridine 16 is obtained by reaction of 8a with elementary sulfur. 16 undergoes cycloaddition with ω-nitrostyrene, maleic anhydride, N-arylmalemide, and acrylonitrile yielding the isoquinolines 21-24. All new compounds have been characterized by their IR, 1H NMR, and mass spectra.
