"Z(OMe)-Met(O)-Gly-OMe" is a peptide-like molecule consisting of three amino acid residues: Z(OMe), Met(O), and Gly, with an additional methoxy group (OMe) attached to the terminal glycine. Z(OMe) represents a protected form of the amino acid methionine, where the sulfur atom is blocked by a methoxy group, preventing unwanted side reactions. Met(O) denotes a methionine residue with an oxygen atom attached to the sulfur, which can be used to introduce specific functional groups or facilitate certain chemical reactions. Gly is the abbreviation for glycine, the simplest amino acid. The molecule is capped with a methoxy group at the C-terminus, which can be used to protect the peptide from further reactions or to facilitate its solubility in organic solvents. Z(OMe)-Met(O)-Gly-OMe is often used in peptide synthesis and as a building block for more complex molecules in chemical biology and medicinal chemistry.
The CAS Registry Mumber 75895-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,8,9 and 5 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 75895-20: (7*7)+(6*5)+(5*8)+(4*9)+(3*5)+(2*2)+(1*0)=174 174 % 10 = 4 So 75895-20-4 is a valid CAS Registry Number.
