"Z-Gly-Phe-Phe-Tyr(But)-AlaOPh" is a peptide sequence consisting of five amino acids: Z-protected glycine (Z-Gly), phenylalanine (Phe), another phenylalanine (Phe), tyrosine with a butyl group (Tyr(But)), and alanine (Ala) with a phenyl group (OPh). This specific sequence is not a naturally occurring peptide but rather a synthetic construct, likely designed for research purposes, such as studying protein-protein interactions, drug development, or understanding the behavior of specific amino acid sequences. The "Z" group is a protecting group used in peptide synthesis to prevent unwanted side reactions, and the "But" indicates a butyl group attached to the tyrosine, which can affect the peptide's properties and interactions. The phenyl group on alanine may also influence the peptide's behavior in biological systems. Overall, this peptide is a synthetic molecule with potential applications in various scientific and medical fields.
The CAS Registry Mumber 86095-66-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,0,9 and 5 respectively; the second part has 2 digits, 6 and 6 respectively. Calculate Digit Verification of CAS Registry Number 86095-66: (7*8)+(6*6)+(5*0)+(4*9)+(3*5)+(2*6)+(1*6)=161 161 % 10 = 1 So 86095-66-1 is a valid CAS Registry Number.
