The chemicals mentioned are two peptide derivatives, which are "N-tert-butoxycarbonyl-glycyl-phenylalanyl-glycine ethyl ester" and "N-tert-butoxycarbonyl-glycyl-L-phenylalanyl-glycine ethyl ester." Both are synthesized by linking glycine (Gly), phenylalanine (Phe), and another glycine residue through peptide bonds. The first compound uses phenylalanine without specifying its chirality, while the second explicitly uses the L-isomer of phenylalanine, which is the naturally occurring form in proteins. These compounds are protected with a tert-butoxycarbonyl (Boc) group, a common strategy in peptide synthesis to prevent unwanted side reactions. The ethyl ester group at the C-terminus of the peptide chain is used to facilitate purification and subsequent reactions. These derivatives are important in the field of peptide chemistry, where they can be used as building blocks for the synthesis of larger peptides or proteins, and the Boc protection allows for controlled deprotection and coupling reactions in peptide synthesis.
The CAS Registry Mumber 3392-14-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,9 and 2 respectively; the second part has 2 digits, 1 and 4 respectively. Calculate Digit Verification of CAS Registry Number 3392-14: (6*3)+(5*3)+(4*9)+(3*2)+(2*1)+(1*4)=81 81 % 10 = 1 So 3392-14-1 is a valid CAS Registry Number.
