Calculate Digit Verification of CAS Registry Number 72559-98:
(7*7)+(6*2)+(5*5)+(4*5)+(3*9)+(2*9)+(1*8)=159
159 % 10 = 9
So 72559-98-9 is a valid CAS Registry Number.

Synthesis and topical antiinflammatory potencies of a series of 6-keto- and Δ6-6-acyloxybetamethasone derivatives

Draper,Berkenkopf,Carlon,Fernandez,Monahan,Lutsky

, p. 317 - 322 (2007/10/02)

6-Keto and Δ6-6-acyloxybetamethasone esters were synthesized, and tested for topical antiinflammatory potency using a modification of the Tonelli croton ear assay. The introduction of a 6-keto group generally led to retention of topical antiinflammatory potencies when compared to the corresponding 6-desoxycorticoids. In contrast, introduction of the Δ6-6-acyloxy moiety into betamethasone 17,21-dipropionate reduced antiinflammatory potency.
