"Z-Ile-Arg(Mds)-Pro-Lys(Boc)-Leu-Lys(Boc)-OBut" is a peptide sequence consisting of seven amino acids. The sequence starts with Z-Ile, which is isoleucine with a benzyloxycarbonyl (Z) protecting group. This is followed by Arg(Mds), an arginine with a 4-methylbenzenesulfonyl (Mds) protecting group. The sequence continues with proline (Pro), Lys(Boc), leucine (Leu), another Lys(Boc), and ends with a butyl ester (OBut). The Boc protecting groups on the lysine residues prevent unwanted side reactions during peptide synthesis. This specific sequence is likely used in research or pharmaceutical applications, where the protecting groups are crucial for controlling the reactivity of the peptide during synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 80220-25-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,2,2 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 80220-25:
(7*8)+(6*0)+(5*2)+(4*2)+(3*0)+(2*2)+(1*5)=83
83 % 10 = 3
So 80220-25-3 is a valid CAS Registry Number.
