Check Digit Verification of cas no

The CAS Registry Mumber 205807-93-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,8,0 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 205807-93:
(8*2)+(7*0)+(6*5)+(5*8)+(4*0)+(3*7)+(2*9)+(1*3)=128
128 % 10 = 8
So 205807-93-8 is a valid CAS Registry Number.

Postsynthetic Modification of Phenylalanine Containing Peptides by C-H Functionalization

Terrey, Myles J.,Perry, Carole C.,Cross, Warren B.

, p. 104 - 108 (2019)

New methods for peptide modification are in high demand in drug discovery, chemical biology, and materials chemistry; methods that modify natural peptides are particularly attractive. A Pd-catalyzed, C-H functionalization protocol for the olefination of phenylalanine residues in peptides is reported, which is compatible with common amino acid protecting groups, and the scope of the styrene reaction partner is broad. Bidentate coordination of the peptide to the catalyst appears crucial for the success of the reaction.
