"Z-D-Phe-ε-Z-L-Lys-OEt" is a peptide compound consisting of three amino acids: D-phenylalanine (D-Phe), ε-lysine (ε-Lys), and L-lysine (L-Lys). The "Z" groups are protecting groups, which are temporary chemical modifications used in peptide synthesis to prevent unwanted side reactions. The "OEt" indicates that the compound is an ethyl ester, which is a common way to protect the carboxyl group of the C-terminal amino acid. This specific peptide is of interest in the field of medicinal chemistry and drug development, as it may have potential applications in the design of new therapeutic agents. The sequence and protection of the amino acids are crucial for the compound's stability and reactivity during synthesis, and the ethyl ester group can be removed under specific conditions to reveal the free carboxyl group, which is often necessary for further reactions or biological activity.

Check Digit Verification of cas no

The CAS Registry Mumber 1436-74-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,3 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1436-74:
(6*1)+(5*4)+(4*3)+(3*6)+(2*7)+(1*4)=74
74 % 10 = 4
So 1436-74-4 is a valid CAS Registry Number.
