Check Digit Verification of cas no

The CAS Registry Mumber 119015-44-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,0,1 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 119015-44:
(8*1)+(7*1)+(6*9)+(5*0)+(4*1)+(3*5)+(2*4)+(1*4)=100
100 % 10 = 0
So 119015-44-0 is a valid CAS Registry Number.

Synthesis and antibacterial activity of new 7-(aminoazabicycloalkanyl)quinolonecarboxylic acids

Ogata, M,Matsumoto, H,Shimizu, S,Kida, S,Nakai, H,et al.

, p. 889 - 906 (2007/10/02)

A series of novel 7--6-fluoro-1-substituted quinolinecarboxylic acids (18-53) have been prepared and their antibacterial activities evaluated.These compounds are characterized structurally by a new amino-substituted azabicyclooctane, -nonane and -decane ring systems at the 7-position of quinolonecarboxylic acids.To compare the biological activities of enantiomers, (+)-7-octan-3-yl>-1-cyclopropyl-6,8-difluoro-1,4-dihydro-4-oxo-3-quinolonecarboxylicacid hydrochloride (43, 44) were synthesized and evaluated for antibacterial activity.Compound 43 was more potent than 44 against both Gram-positive and Gram-negative organisms.The structure-activity relationships of these quinolonecarboxylic acids are also discussed. antibacterial activity / amino-substituted azabicycloalkane ring / substituted quinolonecarboxylic acids / structure-activity relationships
