"Z(OMe)-Ala-Asp(OChp)-Gly-OBzl" is a peptide compound consisting of four amino acids: Z(OMe)-alanine, aspartic acid (Asp), glycine, and benzyloxycarbonyl (OBzl). The Z(OMe) group is a protecting group for the alanine amino acid, while the OChp group is a protecting group for the aspartic acid. The peptide is synthesized with these protecting groups to prevent unwanted side reactions during the synthesis process. The benzyloxycarbonyl group is also a protecting group, which is commonly used to protect the amino group of glycine. This specific peptide sequence is often used in the study of peptide synthesis, drug development, and understanding protein-protein interactions.
The CAS Registry Mumber 98477-97-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,7 and 7 respectively; the second part has 2 digits, 9 and 7 respectively. Calculate Digit Verification of CAS Registry Number 98477-97: (7*9)+(6*8)+(5*4)+(4*7)+(3*7)+(2*9)+(1*7)=205 205 % 10 = 5 So 98477-97-5 is a valid CAS Registry Number.
