N-p-methoxybenzyloxycarbonyl-L-phenylglycine, also known as Z-L-phenylglycine, is a chemical compound with the molecular formula C16H17NO5. It is a derivative of phenylglycine, an amino acid, where the amino group is protected by a p-methoxybenzyloxycarbonyl (Z) group. This protection is crucial in peptide synthesis, as it prevents unwanted side reactions and allows for the controlled formation of peptide bonds. Z-L-phenylglycine is a key building block in the synthesis of various peptides and proteins, and its use is widespread in pharmaceutical and biotechnological research due to its ability to facilitate the assembly of complex molecular structures.

Check Digit Verification of cas no

The CAS Registry Mumber 3873-21-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,7 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3873-21:
(6*3)+(5*8)+(4*7)+(3*3)+(2*2)+(1*1)=100
100 % 10 = 0
So 3873-21-0 is a valid CAS Registry Number.

Synthesis of 1-(t-butoxycarbonyl)benzotriazole and 1-(p-methoxybenzyloxycarbonyl)benzotriazole and their use in the protection of amino acids

Katritzky, Alan R.,Fali, Clara N.,Li, Jianqing,Ager, David J.,Prakash, Indra

, p. 1623 - 1630 (1997)

Benzotriazol-1-ylcarbonyl chloride, generated from benzotriazole and phosgene, reacts with t-butyl alcohol and p-methoxybenzyl alcohol to give 1-(t-butoxycarbonyl)benzotriazole (4) and 1-(p-methoxybenzyloxycarbonyl)benzotriazole (5), respectively in good yields. The synthetic utility of ragents 4 and 5 is shown by effective amino protection in phenylalanine and phenylglycine.
