"Z(OMe)-Gly-Gly-Phe-Leu-OBzl" is a peptide compound consisting of five amino acids: Z(OMe)-protected glycine, glycine, phenylalanine, and leucine, with a benzyl ester group at the C-terminus. The Z(OMe) group is a protecting group for the N-terminus, which is crucial for preventing unwanted side reactions during peptide synthesis. This specific sequence of amino acids is of interest in the field of peptide chemistry, potentially for studying protein-protein interactions, drug design, or as a component in the development of bioactive molecules. The benzyl ester at the end of the peptide serves as a protecting group for the carboxylic acid, which can be removed under specific conditions to reveal the free acid form, a common step in peptide synthesis and purification processes.

Check Digit Verification of cas no

The CAS Registry Mumber 98908-58-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,9,0 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 98908-58:
(7*9)+(6*8)+(5*9)+(4*0)+(3*8)+(2*5)+(1*8)=198
198 % 10 = 8
So 98908-58-8 is a valid CAS Registry Number.
