"Z-GlyIleValGlu(OBut)Gln(Mbh)-OH" is a peptide compound consisting of five amino acids: glycine (Gly), isoleucine (Ile), valine (Val), glutamic acid (Glu), and glutamine (Gln). The peptide is synthesized with a Z-group (benzyloxycarbonyl) protecting group at the N-terminus, which is commonly used to prevent unwanted side reactions during peptide synthesis. The glutamic acid residue has an O-butyryl group attached to its side chain, while the glutamine residue has a 4-methylbenzyl (Mbh) protecting group on its side chain. This specific sequence and modification pattern make "Z-GlyIleValGlu(OBut)Gln(Mbh)-OH" a unique peptide with potential applications in various fields, such as pharmaceuticals, research, and drug development.
The CAS Registry Mumber 77753-41-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,5 and 3 respectively; the second part has 2 digits, 4 and 1 respectively. Calculate Digit Verification of CAS Registry Number 77753-41: (7*7)+(6*7)+(5*7)+(4*5)+(3*3)+(2*4)+(1*1)=164 164 % 10 = 4 So 77753-41-4 is a valid CAS Registry Number.
