Check Digit Verification of cas no

The CAS Registry Mumber 186503-37-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,5,0 and 3 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 186503-37:
(8*1)+(7*8)+(6*6)+(5*5)+(4*0)+(3*3)+(2*3)+(1*7)=147
147 % 10 = 7
So 186503-37-7 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.
