"Z-Ile-Ser(Dpp)-Leu-OBut" is a peptide compound consisting of four amino acids: Isoleucine (Ile), Serine (Ser) with a Dpp (Dipyrromethane) group, Leucine (Leu), and a tert-butyl (OBut) protecting group. The "Z" prefix indicates the presence of a benzyloxycarbonyl (Cbz) protecting group on the N-terminus, which is commonly used in peptide synthesis to prevent unwanted side reactions. This specific sequence and structure are likely designed for a particular biological or chemical purpose, such as mimicking a natural peptide sequence or serving as a substrate for enzyme studies. The Dpp group on Serine may provide unique properties or reactivity, while the OBut group on the C-terminus serves to protect the carboxylic acid group, which is crucial for maintaining the integrity of the peptide during synthesis. Z-Ile-Ser(Dpp)-Leu-OBut represents a sophisticated example of peptide chemistry, where the choice of amino acids and protecting groups is tailored to specific research or therapeutic applications.

Check Digit Verification of cas no

The CAS Registry Mumber 75816-64-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,8,1 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 75816-64:
(7*7)+(6*5)+(5*8)+(4*1)+(3*6)+(2*6)+(1*4)=157
157 % 10 = 7
So 75816-64-7 is a valid CAS Registry Number.
