878679-04-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 878679-04-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,8,6,7 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 878679-04:
(8*8)+(7*7)+(6*8)+(5*6)+(4*7)+(3*9)+(2*0)+(1*4)=250
250 % 10 = 0
So 878679-04-0 is a valid CAS Registry Number.

Novel one pot synthesis of azolo[1,5-a]pyridines from Viehe's salts
Kiselyov, Alexander S.
, p. 1395 - 1398 (2006)
We have developed a practical procedure for the synthesis of polyfunctional azolo[1,5-a]pyridines via the reactive species generated in situ from N-substituted lactams and Viehe's salt. The reaction is regioselective with respect to the nucleophilic addit
