Check Digit Verification of cas no

The CAS Registry Mumber 527755-11-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,7,7,5 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 527755-11:
(8*5)+(7*2)+(6*7)+(5*7)+(4*5)+(3*5)+(2*1)+(1*1)=169
169 % 10 = 9
So 527755-11-9 is a valid CAS Registry Number.

MetAP-2 Inhibitors Based on the Fumagillin Structure. Side-Chain Modification and Ring-Substituted Analogues

Rodeschini, Vincent,Boiteau, Jean-Guy,Van De Weghe, Pierre,Tarnus, Celine,Eustache, Jacques

, p. 357 - 373 (2007/10/03)

The preparation of a series of new fumagillin-derived MetAP-2 inhibitors is described. The synthetic approach was designed so as to permit modification of the fumagillin backbone at sites inaccessible through semisynthesis or previously existing total syntheses. An Evans aldolization and a ring-closing metathesis allowed the preparation of a pivotal intermediate which could then be functionalized in various ways using already established or newly developed methodologies.
