Calculate Digit Verification of CAS Registry Number 204376-70:
(8*2)+(7*0)+(6*4)+(5*3)+(4*7)+(3*6)+(2*7)+(1*0)=115
115 % 10 = 5
So 204376-70-5 is a valid CAS Registry Number.

Novel preparation of 1,1-dioxo-7α-methoxy-3-methyl-Δ3 -cephem-4-yl aryl ketones

Alpegiani, Marco,Bissolino, Pierluigi,D'Anello, Matteo,Perrone, Ettore

, p. 319 - 321 (2007/10/03)

1,1-Dioxo-7α-methoxy-3-methyl-Δ3-cephem-4-yl phenyl ketone, a valuable precursor of potent HLE inhibitors, was obtained in an efficient way starting from 7α-methoxy-3-methyl-Δ3-cephem-4-carboxylic acid. By employing the same methodology a variety of 1,1-dioxocephem-4-yl aryl ketones were prepared.
