"Z(OMe)-Asp(OBzl)-Lys(Z)-OBzl" is a complex peptide compound consisting of four amino acids: Z(OMe)-Asp, OBzl-Lys, and two Z-protected amino acids. Z(OMe)-Asp refers to aspartic acid with a Z(OMe) protecting group, which is a benzyloxycarbonyl (Z) group attached to the side chain hydroxyl group. OBzl-Lys denotes lysine with an OBzl protecting group, which is a benzyl (OBzl) group attached to the side chain amino group. The two Z-protected amino acids are likely to be the terminal amino acids in the peptide sequence, with Z groups protecting their amino groups. This specific arrangement of amino acids and protecting groups is crucial for the peptide's stability and reactivity during synthesis, as it prevents unwanted side reactions and ensures the correct formation of peptide bonds. The compound is often used in peptide synthesis, where the protecting groups are strategically placed to facilitate the stepwise assembly of the peptide chain and are later removed to yield the final product.
The CAS Registry Mumber 65001-82-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,0,0 and 1 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 65001-82: (7*6)+(6*5)+(5*0)+(4*0)+(3*1)+(2*8)+(1*2)=93 93 % 10 = 3 So 65001-82-3 is a valid CAS Registry Number.
