Check Digit Verification of cas no

The CAS Registry Mumber 1309251-02-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,2,5 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1309251-02:
(9*1)+(8*3)+(7*0)+(6*9)+(5*2)+(4*5)+(3*1)+(2*0)+(1*2)=122
122 % 10 = 2
So 1309251-02-2 is a valid CAS Registry Number.

New potential renin inhibitors with dipeptide replacements in the molecule

Winiecka, Iwona,Dudkiewicz-Wilczynska, Jadwiga,Roman, Iza,Paruszewski, Ryszard

, p. 367 - 374 (2011/08/04)

A series of eight non-peptidic potential renin inhibitors have been designed and synthesized. All of them contain dipeptide replacement: (3S,4S)-4-amino-5-cyclohexyl-3-hydroxypentanoic acid (ACHPA) in their molecules. Four among them comprise two additional analogs of dipeptide: (3S,4S)-4-amino-3-hydroxy-5-phenylpentanoic acid (AHPPA) and (3S,4S)-4-amino-3-hydroxy-6-methylheptanoic acid (statine, Sta). All of the synthesized compounds contain also hydrophobic portions to receive a moderate lipophilicity of the molecules. Inhibitory activity of the compounds was measured in vitro by HPLC determination of Leu-Val-Tyr-Ser released from the N-acetyltetradecapeptide substrate by renin in the presence of the inhibitor. Asp-α(OEt)-(S,S)-ACHPA-εAhx-Iaa (23) shows inhibitory activity (7%) at the concentration of 1.0 × 10-2 M. The other synthesized compounds show no inhibitory activity up to this concentration.
