201023-39-4 Usage
General Description
Phenylalanine is an essential amino acid that is crucial for the production of proteins and neurotransmitters in the body. It is found in many protein-rich foods, such as meat, fish, dairy, and eggs. Phenylalanine is also used as a nutritional supplement and is often added to some artificially sweetened products. In the body, phenylalanine is converted into tyrosine, which is important for the production of dopamine, epinephrine, and norepinephrine, all of which are vital for mood regulation and stress response. However, phenylalanine must be carefully monitored in individuals with phenylketonuria, a genetic disorder that impairs the body's ability to process this amino acid.
Check Digit Verification of cas no
The CAS Registry Mumber 201023-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,0,2 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 201023-39:
(8*2)+(7*0)+(6*1)+(5*0)+(4*2)+(3*3)+(2*3)+(1*9)=54
54 % 10 = 4
So 201023-39-4 is a valid CAS Registry Number.

Biomimetic protecting-group-free 2′, 3′-selective aminoacylation of nucleosides and nucleotides
Her, Sohyoung,Kluger, Ronald
supporting information; experimental part, p. 676 - 678 (2011/03/22)
Aminoacyl phosphate monoesters can be prepared free of an amino-protecting group and used directly in lanthanum-promoted selective monoacylation of either the 2′ or 3′-hydroxyl of nucleosides and nucleotides. For example, phenylalanyl ethyl phosphate rapi
