"Z-Phe-Gly-Phe-Leu-Pro-OBut" is a peptide sequence consisting of six amino acids: phenylalanine (Phe), glycine (Gly), phenylalanine (Phe), leucine (Leu), proline (Pro), and a terminal tert-butyloxycarbonyl (OBut) group. This sequence is characterized by its alternating hydrophobic and hydrophilic amino acids, which can influence its solubility and interaction with other molecules. The OBut group is a protecting group commonly used in peptide synthesis to prevent unwanted side reactions, particularly during the coupling of amino acids. Once the peptide is fully synthesized, the OBut group can be removed to reveal the free carboxyl group at the peptide's C-terminus. This specific sequence may have biological activity or be used as a building block in the synthesis of larger peptides or proteins for various applications in research, medicine, or biotechnology.

Check Digit Verification of cas no

The CAS Registry Mumber 74509-19-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,0 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74509-19:
(7*7)+(6*4)+(5*5)+(4*0)+(3*9)+(2*1)+(1*9)=136
136 % 10 = 6
So 74509-19-6 is a valid CAS Registry Number.
