"Z-Glu(O-But)-Asp(Leu-Gly-OH)-OH" is a complex peptide compound consisting of four amino acids: glutamic acid (Glu), aspartic acid (Asp), leucine (Leu), and glycine (Gly). The peptide is synthesized with a carbobenzoxy (Z) group protecting the N-terminus of glutamic acid, an O-butyl group protecting the side chain of aspartic acid, and a hydroxyl group (OH) at both the N-terminus and C-terminus. This specific arrangement and protection of functional groups are crucial for maintaining the peptide's stability and preventing unwanted side reactions during synthesis. The sequence Leu-Gly is linked to the side chain of aspartic acid, creating a unique structure with potential applications in pharmaceuticals, research, and other fields where specific peptide sequences are required.
The CAS Registry Mumber 80451-96-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,5 and 1 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 80451-96: (7*8)+(6*0)+(5*4)+(4*5)+(3*1)+(2*9)+(1*6)=123 123 % 10 = 3 So 80451-96-3 is a valid CAS Registry Number.
