Check Digit Verification of cas no

The CAS Registry Mumber 211692-02-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,6,9 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 211692-02:
(8*2)+(7*1)+(6*1)+(5*6)+(4*9)+(3*2)+(2*0)+(1*2)=103
103 % 10 = 3
So 211692-02-3 is a valid CAS Registry Number.

Ansa macrolides as molecular workbenches: Stereocontrolled syn additions to E olefins

Mulzer, Johann,Schein, Karin,Bats, Jan W.,Buschmann, Juergen,Luger, Peter

, p. 1566 - 1569 (2007/10/03)

Fixed on an aromatic platform in a conformationally defined way, acyclic (E)-alkenes can be considered gripped on a molecular workbench. The olefinic ansa-macrolides formed in this way are shielded on one face. On epoxidation and dihydroxylation [Eq. (1)] the attack on the double bond takes place diastereoselectively from outside the ring, and the ansa chain can subsequently be cleaved from the workbench by mild hydrogenolysis. Bn = benzyl, NMO = N-methylmorpholin-N-oxide.
