The chemical sequence "Z-Pro-Lys(Boc)-Glu(OBut)-Gln-Lys(Boc)-Tyr-Ser-Phe-OBut" represents a peptide, which is a chain of amino acids. In this specific peptide, the amino acids are protected with different protecting groups to prevent unwanted side reactions during synthesis. The "Z" group is a benzyloxycarbonyl (Cbz) protecting group attached to the N-terminus of the peptide, which is commonly used to protect the α-amino group. "Boc" is a tert-butyloxycarbonyl protecting group attached to the side chains of lysine residues, which protects the ε-amino group. "OBut" is a tert-butyl ester protecting group attached to the side chains of glutamic acid and serine residues, which protects the carboxylic acid groups. The sequence includes the amino acids proline (Pro), lysine (Lys), glutamic acid (Glu), glutamine (Gln), tyrosine (Tyr), and phenylalanine (Phe). This peptide is a complex structure with specific protective groups that are crucial for its synthesis and stability.

Check Digit Verification of cas no

The CAS Registry Mumber 79432-32-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,4,3 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 79432-32:
(7*7)+(6*9)+(5*4)+(4*3)+(3*2)+(2*3)+(1*2)=149
149 % 10 = 9
So 79432-32-9 is a valid CAS Registry Number.
