Z-Asp(O-tBu)-Ser-OMe is a peptide derivative consisting of three amino acid residues: aspartic acid (Asp), serine (Ser), and a terminal methoxy group (OMe). The aspartic acid residue is protected with a tert-butyl (tBu) group on its side chain, which is commonly used in peptide synthesis to prevent unwanted side reactions. The serine residue is unmodified, and the terminal methoxy group serves as a protecting group for the carboxylic acid functionality. Z-Asp(O-tBu)-Ser-OMe is often used as a building block in the synthesis of larger peptides and proteins, as well as in the study of peptide conformation and interactions. The Z group, or benzyloxycarbonyl (Z), is a protecting group for the N-terminus of the peptide, which can be removed under mild acidic conditions to reveal the free amine group for further elongation or modification.

Check Digit Verification of cas no

The CAS Registry Mumber 7646-47-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,4 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7646-47:
(6*7)+(5*6)+(4*4)+(3*6)+(2*4)+(1*7)=121
121 % 10 = 1
So 7646-47-1 is a valid CAS Registry Number.
