"Z-Cys(CONHC2H5)-Thr-NH2" is a peptide compound consisting of three amino acids: Cysteine (Cys), Threonine (Thr), and a modified Cysteine with an ethylamide group (CONHC2H5). The "Z" prefix indicates the presence of a carbobenzoxy (Cbz) protecting group, which is commonly used in peptide synthesis to protect the amino group and facilitate stepwise assembly. This specific sequence is of interest in biochemistry and pharmaceuticals, potentially for its role in protein structure or as a component in drug design. The ethylamide modification on the cysteine residue suggests a tailored chemical property, which could influence the peptide's reactivity, stability, or interaction with other molecules.
The CAS Registry Mumber 49706-00-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,7,0 and 6 respectively; the second part has 2 digits, 0 and 0 respectively. Calculate Digit Verification of CAS Registry Number 49706-00: (7*4)+(6*9)+(5*7)+(4*0)+(3*6)+(2*0)+(1*0)=135 135 % 10 = 5 So 49706-00-5 is a valid CAS Registry Number.
