Check Digit Verification of cas no

The CAS Registry Mumber 90252-77-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,5 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90252-77:
(7*9)+(6*0)+(5*2)+(4*5)+(3*2)+(2*7)+(1*7)=120
120 % 10 = 0
So 90252-77-0 is a valid CAS Registry Number.

Optical Resolution and Determination of Absolute Configuration of (=/-)-2-propionic Acids

Naruto, Shunji,Terada, Atsusuke

, p. 4286 - 4294 (2007/10/02)

The title compound, which was newly synthesized, showed good anti-inflammatory and analgesic activities.Optical resolution was performed by the following procedures: 1) condensation of the acid with (-)-1-phenylethylamine followed by separation of diasteromeric amides; 2) reduction of the cyclopentanone moiety and then acylation with optically active acid; 3) separation of epimeric esters followed by saponification of esters; 4) oxidation of alcohols to ketones; 5) saponification of amides.The absolute configurations of the four optically active compounds thus obtained were confirmed by circular dichroism spectroscopy.Keywords -- antiflammatory agent; 2-arylpropionic acid derivative; optical resolution; absolute configuration; CD; ORD
