N--Phe-benzylester is a complex organic compound with the chemical formula C34H47NO5. It is a derivative of phenylalanine, an essential amino acid, with a p-decyloxy-benzyloxy-carbonyl group attached to the nitrogen atom and a benzyl ester group at the carboxylic acid end. N--Phe-benzylester is often used in peptide synthesis as a protecting group for phenylalanine residues, which helps prevent unwanted side reactions during the assembly of peptide chains. The p-decyloxy-benzyloxy-carbonyl group serves as a temporary protective cap, while the benzyl ester group can be easily removed under specific conditions to free the carboxylic acid group for further reactions. N--Phe-benzylester plays a crucial role in the synthesis of biologically active peptides and proteins, allowing chemists to control the sequence and structure of these molecules with precision.

5009-57-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5009-57-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,0 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5009-57:
(6*5)+(5*0)+(4*0)+(3*9)+(2*5)+(1*7)=74
74 % 10 = 4
So 5009-57-4 is a valid CAS Registry Number.
