"Z-Ser(But)-Glu(OBut)-Leu-OH" is a peptide compound consisting of four amino acids: serine (Ser), glutamic acid (Glu), and leucine (Leu). The "Z" group is a protecting group used in peptide synthesis to prevent unwanted side reactions. The "But" groups are tert-butyl protecting groups attached to the serine and glutamic acid residues, which protect the side chain hydroxyl groups during peptide synthesis. The "OH" at the end indicates that the peptide has a free hydroxyl group, which can be used for further reactions or as a terminal group. This peptide is a synthetic analog of a natural peptide sequence and can be used in various applications, such as drug development, research, or as a building block for larger peptide structures.

Check Digit Verification of cas no

The CAS Registry Mumber 98318-18-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,3,1 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 98318-18:
(7*9)+(6*8)+(5*3)+(4*1)+(3*8)+(2*1)+(1*8)=164
164 % 10 = 4
So 98318-18-4 is a valid CAS Registry Number.
