"Z(OMe)-Leu-His-Val-NHNH2" is a peptide compound consisting of four amino acids: Leucine (Leu), Histidine (His), Valine (Val), and a terminal amino group (NHNH2). The "Z(OMe)" prefix indicates that the peptide is protected with a benzyloxycarbonyl (Z) group, which is a common protecting group in peptide synthesis to prevent unwanted side reactions. This specific peptide sequence is of interest in the field of biochemistry and pharmaceuticals, potentially for its role in protein structure or as a component in drug design. The presence of histidine, with its imidazole side chain, suggests that this peptide may have unique chemical properties or be involved in specific biochemical interactions, such as metal binding or proton transfer.
The CAS Registry Mumber 80503-77-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,0 and 3 respectively; the second part has 2 digits, 7 and 7 respectively. Calculate Digit Verification of CAS Registry Number 80503-77: (7*8)+(6*0)+(5*5)+(4*0)+(3*3)+(2*7)+(1*7)=111 111 % 10 = 1 So 80503-77-1 is a valid CAS Registry Number.
