The given sequence of chemicals represents a series of transformations involving the synthesis and modification of amino acid derivatives. Starting with "O-ethyl-N-trifluoroacetyl-L-γ-glutamyl," O-ethyl-N-trifluoroacetyl-L-γ-glutamyl=>O-methyl-L-α-glutamyl=>glycine ethyl ester undergoes a deprotection reaction to remove the trifluoroacetyl group, resulting in "O-ethyl-L-γ-glutamyl." Subsequently, the γ-glutamyl group is further modified to an α-glutamyl group, leading to the formation of "O-methyl-L-α-glutamyl." The final step involves the hydrolysis or cleavage of the peptide bond, yielding glycine ethyl ester. This process showcases the chemical manipulation of amino acid derivatives, which is common in peptide synthesis and pharmaceutical chemistry.
The CAS Registry Mumber 584-64-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,8 and 4 respectively; the second part has 2 digits, 6 and 4 respectively. Calculate Digit Verification of CAS Registry Number 584-64: (5*5)+(4*8)+(3*4)+(2*6)+(1*4)=85 85 % 10 = 5 So 584-64-5 is a valid CAS Registry Number.
