"Z-Val-Tyr-Pro-Asn-Gly-OBzl" is a peptide sequence consisting of six amino acids: Valine (Val), Tyrosine (Tyr), Proline (Pro), Asparagine (Asn), and Glycine (Gly), with a benzyloxycarbonyl (OBzl) protecting group. This sequence is often used in peptide synthesis as a building block for larger proteins or as a model for studying protein-protein interactions. The OBzl group is a temporary protecting group that shields the carboxylic acid group of the terminal amino acid, preventing unwanted side reactions during peptide synthesis. Once the peptide is fully synthesized, the OBzl group can be removed to expose the free carboxylic acid, allowing for further reactions or functionalization. This peptide sequence is of interest in biochemistry and medicinal chemistry for its potential applications in drug development and understanding protein structure and function.
The CAS Registry Mumber 78452-34-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,4,5 and 2 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 78452-34: (7*7)+(6*8)+(5*4)+(4*5)+(3*2)+(2*3)+(1*4)=153 153 % 10 = 3 So 78452-34-3 is a valid CAS Registry Number.
