691860-37-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 691860-37-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,1,8,6 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 691860-37:
(8*6)+(7*9)+(6*1)+(5*8)+(4*6)+(3*0)+(2*3)+(1*7)=194
194 % 10 = 4
So 691860-37-4 is a valid CAS Registry Number.

Post-synthetic functionalization of tryptophan protected peptide sequences through indole (C-2) photocatalytic alkylation

Ackermann, Lutz,Berlinck, Roberto G. S.,Bernardi, Darlon I.,Delgado, José A. C.,Kaplaneris, Nikolaos,Lima, Rafaely N.,Paix?o, Márcio W.

supporting information, p. 5758 - 5761 (2021/06/16)

We report a selective, mild, and efficient C-H functionalization of tryptophan and tryptophan-containing peptides with activated α-bromo-carbonyl compounds under visible-light irradiation. The protocol efficiency is outlined by the wide substrate scope and excellent tolerance of sensitive functional groups present in the amino acid side chains. The method can be successfully extended to access pharmaco-peptide conjugate scaffolds.

Useful synthesis of aryl cinnamates: synthesis of difengpin
