143882-76-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143882-76-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,8 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 143882-76:
(8*1)+(7*4)+(6*3)+(5*8)+(4*8)+(3*2)+(2*7)+(1*6)=152
152 % 10 = 2
So 143882-76-2 is a valid CAS Registry Number.

Synthesis of aminopyridines from azidopyridines and tetrazolo[1,5-a]pyridines
Mekheimer
, p. 322 - 324 (2007/10/02)
3-Cyano-1,2-dihydro-pyridine-2-ones 2 have been synthesized via the base-catalyzed cycloaddition of arylidenecyanoacetamide 1 with acetophenone. Chlorination of 2 with POCl3/PCl5 mixture gave the corresponding chloropyridines 3. Reac
