"Z-histidyl-D-sarcolysyl-Nε-Z-lysyl-tryptophyl-glycine methyl ester" is a complex peptide compound consisting of several amino acids. It is a derivative of the naturally occurring peptide, with the addition of protecting groups (Z) on the histidine and lysine residues, and a methyl ester group on the glycine. The presence of D-sarcolysine, which is the D-isomer of sarcosine, adds to the complexity of the molecule. This synthetic peptide is often used in research to study protein structure, function, and interactions, as well as in the development of new drugs and therapeutics. The specific sequence and modifications can influence its biological activity, stability, and potential applications in various fields, including medicine and biotechnology.
The CAS Registry Mumber 85642-45-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,6,4 and 2 respectively; the second part has 2 digits, 4 and 5 respectively. Calculate Digit Verification of CAS Registry Number 85642-45: (7*8)+(6*5)+(5*6)+(4*4)+(3*2)+(2*4)+(1*5)=151 151 % 10 = 1 So 85642-45-1 is a valid CAS Registry Number.
