"Z(OMe)-Ile-Ala-Ala-OMe" is a peptide compound consisting of four amino acids: Isoleucine (Ile), Alanine (Ala), Alanine (Ala), and a terminal methoxy group (OMe). The "Z(OMe)" prefix indicates the presence of a benzyloxycarbonyl (Z) protecting group on the N-terminus, which is commonly used in peptide synthesis to prevent unwanted side reactions. The peptide is characterized by its sequence of Ile-Ala-Ala, with the terminal methoxy group providing a stable, non-reactive end to the molecule. This specific arrangement of amino acids and protective groups is important in the context of peptide chemistry, as it can influence the peptide's stability, solubility, and potential biological activity.
The CAS Registry Mumber 74104-99-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,0 and 4 respectively; the second part has 2 digits, 9 and 9 respectively. Calculate Digit Verification of CAS Registry Number 74104-99: (7*7)+(6*4)+(5*1)+(4*0)+(3*4)+(2*9)+(1*9)=117 117 % 10 = 7 So 74104-99-7 is a valid CAS Registry Number.
