228718-03-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 228718-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,7,1 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 228718-03:
(8*2)+(7*2)+(6*8)+(5*7)+(4*1)+(3*8)+(2*0)+(1*3)=144
144 % 10 = 4
So 228718-03-4 is a valid CAS Registry Number.

Efficient syntheses of 2-(3',5'-difluorophenyl)-3-(4'- methylsulfonylphenyl)-cyclopent-2-enone, a potent COX-2 inhibitor

Zhao, Dalian,Feng, Xu,Chen, Cheng-yi,Tillyer, Rich D.,Grabowski, Edward J. J.,Reider, Paul J.,Black, Cameron,Quimet, Nathalie,Prasit, Peppi

, p. 6001 - 6018 (1999)

2-(3',5'-Difluorophenyl)-3-(4'-methylsulfonylphenyl)cyclopent-2-enone (1) displays high selectivity and potency against COX-2. Three efficient syntheses of this diarylcyclopentenone are described. The first approach employs a Suzuki coupling reaction as the key step while the second synthesis features an intramolecular Friedel-Crafts acylation. The third, and preferred route to this compound involves a sequential malonate alkylation and acylation and ring-closure sequence.
