The chemical "t-Butoxycarbonyl-Asn-t-butoxycarbonyl-Lys-Phe-Tyr-Gly-Leu-Met-NH2" is a complex peptide compound consisting of a sequence of amino acids. It is a derivative of a naturally occurring peptide, where the amino acids are linked together in a specific order. The sequence starts with asparagine (Asn) and lysine (Lys), both of which are protected with t-butoxycarbonyl (Boc) groups, a common protecting group in peptide synthesis to prevent unwanted side reactions. Following these are phenylalanine (Phe), tyrosine (Tyr), glycine (Gly), leucine (Leu), and methionine (Met), with the peptide ending in an amide group (NH2). This particular peptide is synthesized for various purposes, such as pharmaceutical research, where it may be used to study the structure and function of proteins or to develop potential therapeutic agents. The Boc groups are typically removed during the final stages of synthesis to yield the desired unprotected peptide.
The CAS Registry Mumber 5899-63-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,9 and 9 respectively; the second part has 2 digits, 6 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5899-63: (6*5)+(5*8)+(4*9)+(3*9)+(2*6)+(1*3)=148 148 % 10 = 8 So 5899-63-8 is a valid CAS Registry Number.
