Check Digit Verification of cas no

The CAS Registry Mumber 185448-66-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,4,4 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 185448-66:
(8*1)+(7*8)+(6*5)+(5*4)+(4*4)+(3*8)+(2*6)+(1*6)=172
172 % 10 = 2
So 185448-66-2 is a valid CAS Registry Number.

Design, synthesis, and evaluation of a depsipeptide mimic of tendamistat

Sefler, Andrea M.,Kozlowski, Marisa C.,Guo, Tao,Bartlett, Paul A.

, p. 93 - 102 (2007/10/03)

The cyclic hexadepsipeptide framework of enniatin B was identified as a template matching the β-turn tripeptide of tendamistat. The modified analog 1 was synthesized as a tendamistat mimic and compared to the acyclic derivative 2 and the tripeptide Ac-Try-Arg-Tyr-OMe. These compounds were assembled from the dimeric esters 3-5. As an inhibitor of α-amylase, 1 is twice as potent as 2 and comparable to the tripeptide. NMR studies of 1 reveal four conformers in equilibrium in a 50:25:15:10 ratio; the ring conformation of the major component is similar to that of the enniatin B template, with the cis geometry of the α-hydroxyisovaleryl-N-methylvaline amide linkage; the other conformers differ in the position or presence of the cis amide linkage.
