"Z-D,L-Asp-β-benzylester-α-cyanmethylester" is a complex chemical compound, which can be broken down into its constituent parts for better understanding. "Z" refers to the Z configuration, indicating the geometric arrangement of the molecule. "D,L-Asp" stands for D,L-aspartic acid, an amino acid that exists in two forms, D and L, which are mirror images of each other. "β-benzylester" signifies that the β-carboxyl group of aspartic acid is esterified with a benzyl group, which is a phenylmethyl group. "α-cyanmethylester" indicates that the α-carboxyl group is esterified with a cyanomethyl group, which contains a cyano group (CN) attached to a methyl group. Z-D,L-Asp-β-benzylester-α-cyanmethylester is often used in peptide synthesis due to its stability and reactivity, allowing for the controlled formation of peptide bonds in a stepwise manner.
The CAS Registry Mumber 94875-02-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,8,7 and 5 respectively; the second part has 2 digits, 0 and 2 respectively. Calculate Digit Verification of CAS Registry Number 94875-02: (7*9)+(6*4)+(5*8)+(4*7)+(3*5)+(2*0)+(1*2)=172 172 % 10 = 2 So 94875-02-2 is a valid CAS Registry Number.
