50903-75-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 50903-75-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,9,0 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 50903-75:
(7*5)+(6*0)+(5*9)+(4*0)+(3*3)+(2*7)+(1*5)=108
108 % 10 = 8
So 50903-75-8 is a valid CAS Registry Number.

Peptide Macrocyclization Assisted by Traceless Turn Inducers Derived from Ugi Peptide Ligation with Cleavable and Resin-Linked Amines
Puentes, Alfredo R.,Morejón, Micjel C.,Rivera, Daniel G.,Wessjohann, Ludger A.
, p. 4022 - 4025 (2017/08/15)
A multicomponent approach enabling the installation of turn-inducing moieties that facilitate the macrocyclization of short and medium-size oligopeptides is described. The strategy comprises the Ugi ligation of peptide carboxylic acids and isocyanopeptide
