The CAS Registry Mumber 82578-50-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,5,7 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 82578-50:
(7*8)+(6*2)+(5*5)+(4*7)+(3*8)+(2*5)+(1*0)=155
155 % 10 = 5
So 82578-50-5 is a valid CAS Registry Number.

Synthesis and properties of nuclear hydroxylated derivatives of flufenamic acid and etofenamate

Boltze,Backer,Kreisfeld

, p. 183 - 186 (2007/10/02)

Synthesis of six nuclear hydroxylated derivatives of flufenamic acid and etofenamate (5-OH-, 4'-OH and 5,4'-(OH2) on a preparative scale is described. All compounds show low toxicity, by only weak anti-inflammatory activity in the rat paw kaolin edema test as compared to 2-(2-hydroxyethoxy)ethyl-N-(α,α,α-trifluoro-m-tolyl)-anthranilate (etofenamate, active substance of Rheumon Gel).
