131131-27-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131131-27-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,3 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131131-27:
(8*1)+(7*3)+(6*1)+(5*1)+(4*3)+(3*1)+(2*2)+(1*7)=66
66 % 10 = 6
So 131131-27-6 is a valid CAS Registry Number.

Synthesis of jasplakinolide analogues containing a novel ω-amino acid

Marimganti, Srinivasa,Yasmeen, Shazia,Fischer, Daniela,Maier, Martin E.

, p. 6687 - 6700 (2007/10/03)

The synthesis of the ω-amino acid 4 is described utilizing a two-dimensional synthesis strategy combined with an enzymatic differentiation of homotopic ester groups. The amino acid 4 features two non-bonded interactions that result in conformational const

SEGMENT COUPLING IN PEPTIDE SYTHESIS-II A SIMPLE PREDICTIVE EQUATION CORRELATING RACEMIZATION AND PRIMARY STRUCTURE

Nguyen, Dung Le,Dormoy, Jean-Robert,Castro, Bertrand,Prevot, Daniel

, p. 4229 - 4238 (2007/10/02)

A predictive equation based on extrathermodynamic assumptions is proposed, that allows the prediction of the degree of epimerization in tripeptide model reactions of condensation of peptide segments as a function of the primary structure.The experimental
