87056-44-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87056-44-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,0,5 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 87056-44:
(7*8)+(6*7)+(5*0)+(4*5)+(3*6)+(2*4)+(1*4)=148
148 % 10 = 8
So 87056-44-8 is a valid CAS Registry Number.

Studies in benzonaphthyridines: Synthesis of benzoimidazonaphthyridines
Bachowska,Zujewska
, p. 105 - 106 (2001)
Benzoimidazonaphthyridines were synthesized and quaternary salts of benzonaphthyridine were studied using cyclization reactions. Structural confirmation of the cyclized products was done by nuclear magnetic resonance (NMR), mass spectroscopy and elemental
