155188-32-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155188-32-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,1,8 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 155188-32:
(8*1)+(7*5)+(6*5)+(5*1)+(4*8)+(3*8)+(2*3)+(1*2)=142
142 % 10 = 2
So 155188-32-2 is a valid CAS Registry Number.

Juergens, Jens,Schedletzky, Holger,Heisig, Peter,Seydel, Joachim K.,Wiedemann, Bernd,Holzgrabe, Ulrike
, p. 179 - 190 (2007/10/03)
A series of quinolones with a systematically varied substitution at the phenyl ring at N1 has been synthesized. Three lipophilicity descriptors (log K, log P, R(m)) and the pK(a) values have been determined as well as the microbiological activity: The MIC
