Check Digit Verification of cas no

The CAS Registry Mumber 220285-03-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,2,8 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 220285-03:
(8*2)+(7*2)+(6*0)+(5*2)+(4*8)+(3*5)+(2*0)+(1*3)=90
90 % 10 = 0
So 220285-03-0 is a valid CAS Registry Number.

Synthesis of D- And L-carbocyclic nucleosides via rhodium-catalyzed asymmetric hydroacylation as the key step

Marce, Patricia,Diaz, Yolanda,Matheu, M. Isabel,Castillon, Sergio

supporting information; experimental part, p. 4735 - 4738 (2009/05/31)

(Chemical Equation Presented) D- and L-carbocyclic nucleosides were obtained by a new procedure involving an enantioselective rhodium/duphos- catalyzed hydroacylation reaction as the key step. The 3-hydroxymethyl- cyclopentanol intermediate was obtained by stereoselective reduction of ketone and by dynamic kinetic resolution (DKR).

Bisubstrate inhibitors for the enzyme catechol O-methyltransferase (COMT): Dramatic effects of ribose modifications on binding affinity and binding mode

Lerner, Christian,Siegrist, Romain,Schweizer, Eliane,Diederich, Francois,Gramlich, Volker,Jakob-Roetne, Roland,Zuercher, Gerhard,Borroni, Edilio

, p. 1045 - 1062 (2007/10/03)

Inhibition of the enzyme catechol O-methyltransferase (COMT) is of significant interest in the therapy of Parkinson's disease. Described herein are structural analogs of the potent bisubstrate inhibitor (-)-1 (IC50 = 9 nM; Table 1) for COMT, wi
