The chemical "Z(OCH3)-Ala-Ser(CH2-Ph)-OCH2Ph" is a peptide-like molecule consisting of three main components: a protecting group (Z), two amino acids (alanine and serine), and a phenyl group. The "Z" represents a protecting group, which is often used in peptide synthesis to prevent unwanted side reactions. In this case, "Z(OCH3)" indicates that the protecting group is a benzyloxycarbonyl (Z) group with a methoxy group attached. The "Ala" stands for alanine, a nonpolar amino acid, and "Ser" represents serine, a polar amino acid with a hydroxyl group. The "(CH2-Ph)" part signifies that the serine amino acid has a phenyl group attached to its side chain. Finally, "OCH2Ph" indicates that the molecule has a phenyl group attached to an ethylene glycol (CH2) unit. Overall, Z(OCH3)-Ala-Ser(CH2-Ph)-OCH2Ph is a complex peptide with a protecting group and a phenyl group modification, which may have potential applications in pharmaceuticals or chemical research.
The CAS Registry Mumber 67599-77-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,5,9 and 9 respectively; the second part has 2 digits, 7 and 7 respectively. Calculate Digit Verification of CAS Registry Number 67599-77: (7*6)+(6*7)+(5*5)+(4*9)+(3*9)+(2*7)+(1*7)=193 193 % 10 = 3 So 67599-77-3 is a valid CAS Registry Number.
