Z-Phe-Cys(Z)-Gly-OEt is a synthetic peptide consisting of four amino acid residues: phenylalanine (Phe), cysteine with a benzyloxycarbonyl (Z) protecting group (Cys(Z)), glycine (Gly), and an ethyl ester (OEt) at the C-terminus. This peptide is commonly used in chemical synthesis and research, particularly in the study of protein structure and function, as well as in the development of new drugs and therapeutics. The Z protecting group on the cysteine residue is crucial for preventing unwanted side reactions, such as disulfide bond formation, during peptide synthesis. Once the desired peptide is synthesized, the Z group can be removed to expose the free thiol group, allowing for further reactions or studies. The ethyl ester group at the C-terminus can be hydrolyzed to form a carboxylic acid, which can then be used for conjugation or other chemical modifications. Overall, Z-Phe-Cys(Z)-Gly-OEt is a versatile building block in peptide chemistry, offering a range of applications in both research and drug development.

Check Digit Verification of cas no

The CAS Registry Mumber 30577-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,5,7 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 30577-17:
(7*3)+(6*0)+(5*5)+(4*7)+(3*7)+(2*1)+(1*7)=104
104 % 10 = 4
So 30577-17-4 is a valid CAS Registry Number.
