111453-56-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 111453-56-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,4,5 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 111453-56:
(8*1)+(7*1)+(6*1)+(5*4)+(4*5)+(3*3)+(2*5)+(1*6)=86
86 % 10 = 6
So 111453-56-6 is a valid CAS Registry Number.

Ethyl 9-cyclopropyl-4-fluoro-6-oxo-6,9-dihydro[ 1,2,5]oxadiazolo[3,4-h]quinoline-7-carboxylate N(3)-oxide (3) is synthesized via pyrolysis of the 7-azido-8-nitroquinoline-3-carboxylate precursor (6). Acid-catalyzed hydrolysis of the product (3) afforded t

Indolo[2,3-b]-, Indeno[1,2-b]- and Indeno[2,1-b]pyrido[2,3-f] quinoxaline-3-carboxylic acids and esters, processes for their preparation and their use as antiviral, antibiotic and antitumor agents

The present invention relates to novel quinoxaline derivatives represented by regioisomeric structures of quinoxalines of general formulas I and/or II, wherein the COOR1 group independently is an acid, an ester and/or a salt, Y1 and/

Quinolone Antibacterial Agents. Synthesis and Structure-Activity Relationships of 8-Substituted Quinoline-3-carboxylic Acids and 1,8-Naphthyridine-3-carboxylic Acids

Sanchez, Joseph P.,Domagala, John M.,Hagen, Susan E.,Heifetz, Carl L.,Hutt, Marland P.,et al.

, p. 983 - 991 (2007/10/02)

A series of 7,8-disubstituted 1-cyclopropyl-6-fluoroquinoline-3-carboxylic acids, 7-substituted 1-cyclopropyl-6-fluoro-1,8-naphthyridine-3-carboxylic acids, and 10-substituted 9-fluoropyridobenzoxazine-6-carboxylic acids has been prepared and evaluated for antibacterial activity.The side chains examined at the 7-position (benzoxazine 10-position) included piperazinyl (g), 3-aminopyrrolidinyl (a), 3-(aminomethyl)pyrrolidinyl (b), and alkylated 3-(aminomethyl)pyrrolidinyl (c-f).Variations ta C-8 of the quinolone ring system included hydrogen, nitro, amino, fluorine and chlorine.The relative enhancement of in vitro activities by the side chains on the 8-hydrogen quinolone and 1,8-naphthyridine against Gram-negative organisms was a > b > g > c-f.The activity imparted to the substituted quinolone nucleus by the 8-substituent was in the order F > Cl > naphthyridine > H > benzoxazine > NH2 > NO2.These trends were retained in vivo.
