Z-Asn-Thr-NHNH2 is a tripeptide compound, consisting of three amino acids: asparagine (Asn), threonine (Thr), and a terminal amino group (NH2). The "Z" prefix indicates the presence of a carbobenzoxy (Cbz) protecting group, which is commonly used in peptide synthesis to prevent unwanted side reactions. Z-Asn-Thr-NHNH2 is of interest in the field of biochemistry and pharmaceuticals, as it can serve as a building block for larger peptide structures or as a precursor in the synthesis of more complex molecules. The Z-group helps to stabilize the peptide during synthesis, ensuring that the amino acids are correctly linked in the desired sequence. Once the peptide is fully assembled, the Z-group can be removed to reveal the free amino terminus, which is essential for the peptide's biological activity.
The CAS Registry Mumber 75893-41-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,8,9 and 3 respectively; the second part has 2 digits, 4 and 1 respectively. Calculate Digit Verification of CAS Registry Number 75893-41: (7*7)+(6*5)+(5*8)+(4*9)+(3*3)+(2*4)+(1*1)=173 173 % 10 = 3 So 75893-41-3 is a valid CAS Registry Number.
