"Z(OMe)-Val-His-Asn-Phe-Val-Ala-Leu-Gly-OBzl" is a peptide sequence consisting of ten amino acids. It starts with Z(OMe), which is a protecting group for the N-terminus, followed by Valine (Val), Histidine (His), Asparagine (Asn), Phenylalanine (Phe), another Valine (Val), Alanine (Ala), Leucine (Leu), Glycine (Gly), and ends with OBzl, a protecting group for the C-terminus. This specific sequence is often used in peptide synthesis and research, particularly in the development of pharmaceuticals and understanding protein interactions. The protecting groups are crucial for preventing unwanted side reactions during the synthesis process, ensuring that the peptide is formed with the correct structure and functionality.
The CAS Registry Mumber 82882-82-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,8 and 2 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 82882-82: (7*8)+(6*2)+(5*8)+(4*8)+(3*2)+(2*8)+(1*2)=164 164 % 10 = 4 So 82882-82-4 is a valid CAS Registry Number.
