Check Digit Verification of cas no

The CAS Registry Mumber 634893-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,4,8,9 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 634893-99:
(8*6)+(7*3)+(6*4)+(5*8)+(4*9)+(3*3)+(2*9)+(1*9)=205
205 % 10 = 5
So 634893-99-5 is a valid CAS Registry Number.

Strategies and methods for the attachment of amino acids and peptides to chiral [n]polynorbornane templates.

Pfeffer, Frederick M,Russell, Richard A

, p. 1845 - 1851 (2007/10/03)

A versatile synthesis of amino acid and peptide functionalised [n]polynorbornane scaffolds is described. The frameworks are constructed using the stereoselective and regioselective cycloaddition of suitably functionalised chiral cyclobutene epoxides with similar norbornenes. The strategies employed allow a range of topologies to be accessed and a number of regioselectively addressable linkage points to be accommodated.
