The chemical "Z-Gly-Pro-Ser-Asp-Thr(But)-Pro-Ile-Leu-Pro-Gln-OBut" is a peptide compound consisting of a sequence of amino acids. It is a synthetic polypeptide with a molecular structure that includes a series of amino acids linked together by peptide bonds. The sequence starts with a Z group, which is a protecting group used in peptide synthesis to prevent unwanted side reactions. The amino acids in the sequence are glycine (Gly), proline (Pro), serine (Ser), aspartic acid (Asp), threonine with a butyl group (Thr(But)), another proline (Pro), isoleucine (Ile), leucine (Leu), and glutamine (Gln). The sequence ends with an OBut group, which is another protecting group. This peptide is likely used in research or pharmaceutical development due to its specific sequence and protective groups, which can influence its stability, reactivity, and potential biological activity.
The CAS Registry Mumber 75895-03-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,8,9 and 5 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 75895-03: (7*7)+(6*5)+(5*8)+(4*9)+(3*5)+(2*0)+(1*3)=173 173 % 10 = 3 So 75895-03-3 is a valid CAS Registry Number.
