"Z(OMe)-Phe-Leu-OBzl" is a peptide compound consisting of three amino acids: Z(OMe)-protected phenylalanine (Phe), leucine (Leu), and benzyl-protected (OBzl) phenylalanine. The "Z" group is a benzyloxycarbonyl (Cbz) protecting group, while the "OMe" indicates a methoxy group attached to the Z group, which helps in the selective deprotection of the peptide. This specific sequence of amino acids is often used in peptide synthesis and research, as the protecting groups allow for controlled synthesis and manipulation of the peptide chain. The benzyl group on the terminal phenylalanine serves as a temporary protecting group that can be removed under specific conditions to reveal the free amino group, facilitating further peptide bond formation or other chemical modifications.

Check Digit Verification of cas no

The CAS Registry Mumber 98908-56-6 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 6 respectively.
Calculate Digit Verification of CAS Registry Number 98908-56:
(7*9)+(6*8)+(5*9)+(4*0)+(3*8)+(2*5)+(1*6)=196
196 % 10 = 6
So 98908-56-6 is a valid CAS Registry Number.
