1,Nα-bis-(toluene-4-sulfonyl)-histidine is a chemical compound derived from histidine, an essential amino acid. 1,N^α-bis-(toluene-4-sulfonyl)-histidine is characterized by the presence of two tosyl (toluene-4-sulfonyl) groups attached to the nitrogen atom at the α-position of the histidine side chain. The tosyl groups are electron-withdrawing and can influence the reactivity and stability of the histidine residue. This modification is often used in peptide synthesis and protein chemistry to protect the amino group of histidine, preventing unwanted side reactions during the synthesis process. The compound plays a role in various biochemical applications, such as the synthesis of complex peptides and the study of protein folding and interactions.

Check Digit Verification of cas no

The CAS Registry Mumber 2080-76-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,8 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2080-76:
(6*2)+(5*0)+(4*8)+(3*0)+(2*7)+(1*6)=64
64 % 10 = 4
So 2080-76-4 is a valid CAS Registry Number.
