"Z-Ser-Asp(OBzl)-Leu-Pro-Gln-Thr(Bzl)-His-Ser(Bzl)-Leu-Gly-OH" is a peptide sequence consisting of 12 amino acids. It is a synthetic compound with a specific arrangement of amino acids, each denoted by its three-letter code. The sequence starts with a Z group (benzyloxycarbonyl) protecting group on the serine (Ser), followed by aspartic acid (Asp) with a benzyl (OBzl) protecting group, leucine (Leu), proline (Pro), glutamine (Gln), threonine (Thr) with a benzyl protecting group, histidine (His), serine (Ser) with a benzyl protecting group, another leucine (Leu), glycine (Gly), and ends with a hydroxyl (OH) group. This peptide is likely used in research or pharmaceutical development, possibly as a component of a larger protein or for studying protein-protein interactions. The protecting groups are crucial for preventing unwanted side reactions during synthesis and are removed at a later stage to reveal the free amino acid side chains.
The CAS Registry Mumber 79123-65-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,1,2 and 3 respectively; the second part has 2 digits, 6 and 5 respectively. Calculate Digit Verification of CAS Registry Number 79123-65: (7*7)+(6*9)+(5*1)+(4*2)+(3*3)+(2*6)+(1*5)=142 142 % 10 = 2 So 79123-65-2 is a valid CAS Registry Number.
