"Z(OMe)-Lys(Z)-OTCP" is a complex chemical compound, which can be broken down into its constituent parts for better understanding. "Z" stands for the benzyloxycarbonyl group, a protecting group used in peptide synthesis to prevent unwanted side reactions. "OMe" represents the methoxy group, an alkyl group derived from methanol. "Lys(Z)" denotes lysine, an amino acid with a Z group attached to its side chain, which serves as a protecting group during peptide synthesis. "OTCP" stands for octachloropropa-1,3-diene, a highly chlorinated compound used as a pesticide. In summary, "Z(OMe)-Lys(Z)-OTCP" is a chemical compound that combines a protected lysine amino acid with an octachloropropa-1,3-diene moiety, potentially used in the synthesis of complex molecules or as a component in chemical research.
The CAS Registry Mumber 51165-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,1,6 and 5 respectively; the second part has 2 digits, 1 and 7 respectively. Calculate Digit Verification of CAS Registry Number 51165-17: (7*5)+(6*1)+(5*1)+(4*6)+(3*5)+(2*1)+(1*7)=94 94 % 10 = 4 So 51165-17-4 is a valid CAS Registry Number.
