Check Digit Verification of cas no

The CAS Registry Mumber 1020737-23-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,0,7,3 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1020737-23:
(9*1)+(8*0)+(7*2)+(6*0)+(5*7)+(4*3)+(3*7)+(2*2)+(1*3)=98
98 % 10 = 8
So 1020737-23-8 is a valid CAS Registry Number.

Diastereoselective ru-catalyzed cross-metathesis-dihydroxylation sequence. An efficient approach toward enantiomerically enriched syn-diols

Neisius, N. Matthias,Plietker, Bernd

, p. 3218 - 3227 (2008/09/19)

(Chemical Equation Presented) Sequential catalysis has evolved as a powerful concept within the past years and allows the more efficient use of catalytically active expensive transition metals in organic synthesis. In this paper we present the stereoselective cross-metathesis-dihydroxylation of various olefins with chiral auxiliary substituted acrylamides. The chiral information (i.e., the auxiliary) introduced in the metathesis reactions allows for a stereoselective subsequent RuO4-catalyzed dihydroxylation. The sequence is concluded by an unusual kinetic resolution of the diastereomeric diols obtained in the oxidation reaction. As a consequence a variety of structurally diverse enantiomerically enriched diols are obtained. To the best of our knowledge the results summarized in this paper represent the first highly efficient diastereoselective RuO4-catalyzed oxidation.
