3705-50-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3705-50-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,0 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3705-50:
(6*3)+(5*7)+(4*0)+(3*5)+(2*5)+(1*0)=78
78 % 10 = 8
So 3705-50-8 is a valid CAS Registry Number.

Enantioselection in peptide bond formation

Hill, Roger R.,Birch, David,Jeffs, Graham E.,North, Michael

, p. 965 - 972 (2007/10/03)

Selectivity in abiotic condensations of amino acids remains controversial and stereochemically little explored. We find that competitive activated couplings of N-acyl derivatives of glycine, alanine, valine, proline and phenylalanine with binary, ternary and quaternary mixtures of amides and esters of the same group of amino acids show little selectivity among the reactants, except with respect to configuration, where a consistent and significant preference for heterochiral outcomes, mostly >80%, is observed. One possible explanation of this selectivity predicts a predisposition to homochiral coupling under conditions that would require the two carboxyl functions to be co-facial in the activated complex.
