99803-82-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 99803-82-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,0 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 99803-82:
(7*9)+(6*9)+(5*8)+(4*0)+(3*3)+(2*8)+(1*2)=184
184 % 10 = 4
So 99803-82-4 is a valid CAS Registry Number.

5-Substituted 4-isoxazolecarboxamides with platelet antiaggregating and other activities

Fossa,Menozzi,Schenone,Filipelli,Russo,Lucarelli,Marmo

, p. 789 - 802 (2007/10/02)

The synthesis of a series of 5-substituted 4-isoxazolecarboxamides by reaction of eight 5-substituted 4-isoxazolecarbonyl chlorides with pyrrolidine, piperidine, morpholine and 4-trifluoromethylaniline is described. Some of these amides showed platelet antiaggregating activity in vitro slightly inferior to that of acetylsalicylic acid, as well weak antiinflammatory, analgesic and antipyretic activities in rats and mice.
