Check Digit Verification of cas no

The CAS Registry Mumber 169032-05-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,0,3 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 169032-05:
(8*1)+(7*6)+(6*9)+(5*0)+(4*3)+(3*2)+(2*0)+(1*5)=127
127 % 10 = 7
So 169032-05-7 is a valid CAS Registry Number.

Design and scalable synthesis of new chiral selectors. Part 1: Synthesis and characterization of a new constrained cyclopeptide from unnatural bulky amino acids

Ferron, Laurent,Guillen, Frederic,Coste, Servane,Coquerel, Gerard,Cardinael, Pascal,Schwartz, Joel,Paris, Jean-Marc,Plaquevent, Jean-Christophe

scheme or table, p. 6036 - 6044 (2011/09/12)

We describe the conception, synthesis, and characterization of a novel cyclopeptide designed for chiral recognition. The asymmetric units are built from an unnatural amino acid in the series of α-aryl-α-methyl glycine. Modifications of standard methods of peptide synthesis are described in order to improve yields and purities when applied to hindered amino acids. First set of experiments about host-guest ability of the obtained cyclopeptide is disclosed.
