Phe-OEt * TosOH, also known as L-phenylalanine p-toluenesulfonate ethyl ester, is a chemical compound derived from the amino acid L-phenylalanine. It is formed by the esterification of L-phenylalanine with ethanol and the subsequent formation of a tosylate salt. Phe-OEt * TosOH is often used in organic synthesis and peptide chemistry, particularly in the preparation of protected amino acid derivatives. The p-toluenesulfonate (Tos) group serves as a protecting group for the carboxylic acid functionality, while the ethyl ester (OEt) protects the amino group. This allows for controlled reactions and the synthesis of complex molecules without unwanted side reactions. Phe-OEt * TosOH is a white crystalline solid that is soluble in organic solvents and is commonly used in the synthesis of peptides and other biologically active compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 5002-64-2 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 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5002-64:
(6*5)+(5*0)+(4*0)+(3*2)+(2*6)+(1*4)=52
52 % 10 = 2
So 5002-64-2 is a valid CAS Registry Number.
