Z-DL-val-gly-benzylester, also known as Z-DL-Val-Gly-OBzl, is a synthetic peptide derivative that consists of three amino acids: D-leucine (DL-val), glycine (gly), and a benzyl ester group (OBzl). The "Z" in its name stands for the carbobenzyloxy (Cbz) protecting group, which is commonly used in peptide synthesis to protect the amino group of the terminal amino acid. Z-DL-val-gly-benzylester is often utilized in the field of organic chemistry and peptide synthesis, where it serves as a building block for the creation of larger peptides and proteins. The benzyl ester group plays a role in protecting the carboxylic acid group, which is crucial for the stability of the peptide during synthesis. Once the desired peptide sequence is assembled, the protecting groups are removed to yield the final product. Z-DL-val-gly-benzylester is an example of the精细化工 approach to peptide synthesis, highlighting the importance of protecting groups in the construction of complex molecular structures.
The CAS Registry Mumber 97115-05-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,1,1 and 5 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 97115-05: (7*9)+(6*7)+(5*1)+(4*1)+(3*5)+(2*0)+(1*5)=134 134 % 10 = 4 So 97115-05-4 is a valid CAS Registry Number.
