"Z-Asp(OBut)-Asn-Gln-OBut" is a peptide compound consisting of four amino acids: Aspartic acid (Asp), Asparagine (Asn), and Glutamine (Gln). The "Z" group is a protecting group used in peptide synthesis to prevent unwanted side reactions. The "OBut" groups are tert-butyloxycarbonyl protecting groups attached to the side chains of Asp and Gln, which protect the carboxyl groups during peptide synthesis. This specific sequence and protection scheme are crucial for the controlled synthesis of larger peptides or proteins, ensuring that the correct amino acids are linked in the desired order while preventing premature reactions that could disrupt the peptide backbone formation.

Check Digit Verification of cas no

The CAS Registry Mumber 83428-82-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,2 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 83428-82:
(7*8)+(6*3)+(5*4)+(4*2)+(3*8)+(2*8)+(1*2)=144
144 % 10 = 4
So 83428-82-4 is a valid CAS Registry Number.
