L-Tyrosine, O-ethyl-N-formyl-, also known as N-formyl-O-ethyl-L-tyrosine, is a synthetic derivative of the amino acid L-tyrosine. It is characterized by the presence of a formyl group (-CHO) attached to the nitrogen atom and an ethyl group (-C2H5) connected to the hydroxyl group of the tyrosine molecule. This chemical modification alters the properties and potential applications of the original L-tyrosine, which is an essential amino acid involved in the synthesis of neurotransmitters, hormones, and melanin. The derivative may be used in research and development for pharmaceuticals, as a building block in peptide synthesis, or for studying the effects of chemical modifications on protein structure and function.
The CAS Registry Mumber 3909-27-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,0 and 9 respectively; the second part has 2 digits, 2 and 7 respectively. Calculate Digit Verification of CAS Registry Number 3909-27: (6*3)+(5*9)+(4*0)+(3*9)+(2*2)+(1*7)=101 101 % 10 = 1 So 3909-27-1 is a valid CAS Registry Number.
