Check Digit Verification of cas no

The CAS Registry Mumber 93652-02-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,6,5 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 93652-02:
(7*9)+(6*3)+(5*6)+(4*5)+(3*2)+(2*0)+(1*2)=139
139 % 10 = 9
So 93652-02-9 is a valid CAS Registry Number.

New PDE4 inhibitors based on pharmacophoric similarity between papaverine and tofisopam

Bihel, Frédéric J.J.,Justiniano, Héléne,Schmitt, Martine,Hellal, Malik,Ibrahim, Mohamed A.,Lugnier, Claire,Bourguignon, Jean-Jacques

scheme or table, p. 6567 - 6572 (2011/12/04)

Pharmacophoric comparison between papaverine and tofisopam led to identify three new series of microto sub-micromolar inhibitors of phosphodiesterase-4, including 7,8-dialkoxy-2,3-benzodiazepin-4-one derivatives, 7,8-dialkoxy-1,4- benzodiazepin-2-one derivatives, and dialkoxybenzophenone derivatives.

Solvent-free Friedel-Crafts acylation of aromatic compounds with carboxylic acids in the presence of trifluoroacetic anhydride and aluminum dodecatungstophosphate

Firouzabadi, Habib,Iranpoor, Nasser,Nowrouzi, Farhad

, p. 5343 - 5345 (2007/10/03)

The stable and non-hygroscopic aluminum dodecatungstophosphate (AlPW12O40), was found to be an effective catalyst (3 mol%) for the solvent-free Friedel-Crafts acylation of aromatic compounds with carboxylic acids in the presence of trifluoroacetic anhydride under mild reaction conditions.
