"Z(OMe)-Pro-Ser(Bzl)-Ser(Bzl)-OMe" is a peptide-like molecule consisting of a sequence of amino acid derivatives. The "Z" group represents a carbobenzoxy (Cbz) protecting group, which is commonly used in peptide synthesis to protect the amino group. "OMe" stands for methoxy, indicating a methyl ether group. "Pro" is the abbreviation for proline, an amino acid with a cyclic side chain. "Ser" is short for serine, an amino acid with a hydroxyl group in its side chain. The "Bzl" group signifies a benzyl protecting group, which is used to protect the hydroxyl group in serine. This molecule is a protected peptide, where the side chain functional groups are temporarily masked to prevent unwanted side reactions during synthesis. The sequence of the molecule is a proline, followed by two serines, each with a benzyl protecting group, and the entire sequence is capped with a methoxy group at the end. This type of molecule is often used in the synthesis of more complex peptides and proteins, where the protecting groups are removed in a controlled manner to reveal the final product.
The CAS Registry Mumber 96922-08-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,9,2 and 2 respectively; the second part has 2 digits, 0 and 8 respectively. Calculate Digit Verification of CAS Registry Number 96922-08: (7*9)+(6*6)+(5*9)+(4*2)+(3*2)+(2*0)+(1*8)=166 166 % 10 = 6 So 96922-08-6 is a valid CAS Registry Number.
