The chemical "Z-Ser-Asp-Thr(But)-Pro-Ile-Leu-Pro-Gln-OBut" is a peptide sequence consisting of ten amino acids. It is a synthetic compound where each amino acid is linked to the next by peptide bonds. The sequence starts with a Z group (benzyloxycarbonyl), which is a protecting group used in peptide synthesis to prevent unwanted side reactions. The sequence includes serine (Ser), aspartic acid (Asp), threonine with a butyl group (Thr(But)), proline (Pro), isoleucine (Ile), leucine (Leu), another proline, glutamine (Gln), and ends with a tert-butyl group (OBut), which is another protecting group. This specific arrangement of amino acids and protective groups is designed for a particular purpose in chemical or biological research, such as studying protein structure, function, or interactions.
The CAS Registry Mumber 73535-29-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,5,3 and 5 respectively; the second part has 2 digits, 2 and 9 respectively. Calculate Digit Verification of CAS Registry Number 73535-29: (7*7)+(6*3)+(5*5)+(4*3)+(3*5)+(2*2)+(1*9)=132 132 % 10 = 2 So 73535-29-2 is a valid CAS Registry Number.
