"Z-Gly-Val-Ser-D-Phe-Val-Leu-OMe" is a peptide sequence consisting of eight amino acids, with a protecting group (OMe) at the end. The sequence starts with a Z group-protected glycine (Z-Gly), followed by valine (Val), serine (Ser), D-phenylalanine (D-Phe), another valine (Val), and leucine (Leu). The D-Phe indicates that the phenylalanine is in the D-configuration, which is the non-natural isomer of the amino acid. This peptide sequence is likely used in research or pharmaceutical development, as the specific arrangement and protection of these amino acids can influence its properties and interactions within biological systems. The OMe group at the end serves to protect the peptide's terminal carboxyl group, which is important for certain chemical reactions or stability in solution.
The CAS Registry Mumber 95303-67-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,3,0 and 3 respectively; the second part has 2 digits, 6 and 7 respectively. Calculate Digit Verification of CAS Registry Number 95303-67: (7*9)+(6*5)+(5*3)+(4*0)+(3*3)+(2*6)+(1*7)=136 136 % 10 = 6 So 95303-67-6 is a valid CAS Registry Number.
