87694-54-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87694-54-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,9 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 87694-54:
(7*8)+(6*7)+(5*6)+(4*9)+(3*4)+(2*5)+(1*4)=190
190 % 10 = 0
So 87694-54-0 is a valid CAS Registry Number.

Synthesis of new chiral peptide nucleic acid (PNA) monomers by a simplified reductive amination method

Falkiewicz, Bogdan,Kowalska, Katarzyna,Kolodziejczyk, Aleksandra S.,Wisniewski, Kazimierz,Lankiewicz, Leszek

, p. 353 - 361 (1999)

The aim of this work was the preparation of four new peptide nucleic acid (PNA) monomer backbone by reductive amination of N(α)-Boc-protected chiral amino aldehydes, derived from Leu, Phe, Tyr(Bzl), and Thr(Bzl), with methyl glycinate. To the crude 2-subs

Pyrrole-based scaffolds for turn mimics

Ko, Eunhwa,Burgess, Kevin

supporting information; experimental part, p. 980 - 983 (2011/04/22)

Two amino acid derived synthons were combined to give homopropargylic amines 2. Platinum dichloride was used to cyclize these intermediates into pyrroles 3 which collapsed to the target secondary structure mimics 1 on treatment with base. Side chains of these compounds overlay with an idealized type 1 β-turn and with an inverse γ-turn.(Figure Presented)
