N-tert.-Butoxycarbonyl-Ala-Phe-Ile-Gly-Leu--homocystein-amid is a complex peptide compound consisting of seven amino acids: alanine (Ala), phenylalanine (Phe), isoleucine (Ile), glycine (Gly), leucine (Leu), and a modified homocysteine with an S-ethyl group. The N-tert.-butoxycarbonyl group is a protecting group used in peptide synthesis to prevent unwanted side reactions. This specific sequence of amino acids forms a peptide chain with unique properties and potential applications in various fields, such as pharmaceuticals, research, and biotechnology. The structure and composition of this peptide make it an interesting subject for study, as it may exhibit specific biological activities or serve as a building block for more complex molecules.
The CAS Registry Mumber 7199-71-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,9 and 9 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 7199-71: (6*7)+(5*1)+(4*9)+(3*9)+(2*7)+(1*1)=125 125 % 10 = 5 So 7199-71-5 is a valid CAS Registry Number.
