144603-05-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144603-05-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,6,0 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 144603-05:
(8*1)+(7*4)+(6*4)+(5*6)+(4*0)+(3*3)+(2*0)+(1*5)=104
104 % 10 = 4
So 144603-05-4 is a valid CAS Registry Number.

Halogenation Reactions in Position 3 of Quinoline-2,4-dione Systems by Electrophilic Substitution and Halogen Exchange

Stadlbauer, Wolfgang,Laschober, Rita,Lutschounig, Herbert,Schindler, Gerda,Kappe, Thomas

, p. 617 - 636 (2007/10/02)

3-Substituted 4-hydroxy-2(1H)-quinolones 3, 5, 7 are halogenated with bromine or sulfuryl chloride to yield the quinolinediones 9 or 10.Reactions of 3, 5, 7 with chloroform gives the dichloromethyl quinolinediones 11.Halogen exchange leads from the chloro quinolinediones 10 to fluoro quinolinedones 12 and to azido quinolinediones 13.Similarly the dichloro quinolinediones 10an reacts to the difluoro quinolinedione 14, which is reduced to the 3-fluoro-4-hydroxyquinolone 16 and reacts again with sulfuryl chloride to give the mixed 3-chloro-3-fluoroquinolinedione 15.Keywords.Fluorination; 4-Hydroxy-2(1H)-quinolones, 3-alkyl/3-aryl/3-fluoro; 1-Hydroxy-benzoquinolizine-3-ones, 2-alkyl/3-aryl; Quinoline-2,4(1H,3H)-diones, 3-azido-3-alkyl/3-aryl, 3-bromo-3-alkyl/3-aryl, 3-chloro-3-alkyl/3-aryl, 3-fluoro-3-alkyl/3-aryl, 3-dichloromethyl-3-alkyl/3-aryl, 3-chloro-3-fluoro.
