Tert.-butoxycarbonyl-Asn-tert.-butoxycarbonyl-Lys-methylester, also known as Boc-Asn(Boc)-Lys-OMe, is a peptide derivative that consists of three amino acids: asparagine (Asn), lysine (Lys), and a methyl ester group. The Boc (tert-butoxycarbonyl) group is a protecting group used in peptide synthesis to prevent unwanted side reactions, particularly during the coupling of amino acids. In tert.-Butoxycarbonyl-Asn-tert.-butoxycarbonyl-Lys-methylester, both asparagine and lysine are protected with Boc groups, while the terminal amino acid, lysine, is also connected to a methyl ester group. This specific arrangement is crucial for the synthesis of certain peptides and proteins, as it allows for controlled and selective deprotection and coupling reactions. The compound plays a significant role in the field of peptide chemistry, particularly in the synthesis of complex peptide sequences and pharmaceuticals.
The CAS Registry Mumber 6062-53-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,6 and 2 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 6062-53: (6*6)+(5*0)+(4*6)+(3*2)+(2*5)+(1*3)=79 79 % 10 = 9 So 6062-53-9 is a valid CAS Registry Number.
