119877-54-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119877-54-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,8,7 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 119877-54:
(8*1)+(7*1)+(6*9)+(5*8)+(4*7)+(3*7)+(2*5)+(1*4)=172
172 % 10 = 2
So 119877-54-2 is a valid CAS Registry Number.

Synthesis of novel 5-fluoro analogues of norfloxacin and ciprofloxacin
Moran,Ziegler Jr.,Dunne,Kuck,Lin
, p. 1313 - 1318 (2007/10/02)
A series of polyfluoro-3-quinolonecarboxylic acids have been synthesized and their in vitro antibacterial activity evaluated. The desired 7-(substituted amino) derivatives were prepared from the 5,6,7,8-tetrafluoroquinolone acids. Conversely, amine displa
