"Z(OMe)-Asp(OtBu)-Ser(Bzl)-Tyr-OMe" is a peptide sequence consisting of four amino acids: N-benzyloxycarbonyl (Z)-protected aspartic acid (Asp), tert-butyloxycarbonyl (Boc)-protected aspartic acid, benzyl (Bzl)-protected serine (Ser), and tyrosine (Tyr), with a methoxy (OMe) group at the N-terminus and a methoxy (OMe) group at the C-terminus. This specific arrangement of amino acids is designed to protect certain functional groups during peptide synthesis, which is crucial for maintaining the integrity of the peptide and preventing unwanted side reactions. The use of protecting groups like Z, Boc, and Bzl allows for controlled deprotection steps, enabling the synthesis of complex peptides with specific functionalities. The OMe groups at both ends contribute to the stability and solubility of the peptide, which can be important for its biological activity and further chemical modifications.
The CAS Registry Mumber 96922-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,9,2 and 2 respectively; the second part has 2 digits, 2 and 2 respectively. Calculate Digit Verification of CAS Registry Number 96922-22: (7*9)+(6*6)+(5*9)+(4*2)+(3*2)+(2*2)+(1*2)=164 164 % 10 = 4 So 96922-22-4 is a valid CAS Registry Number.
