Uses
Different sources of media describe the Uses of 21820-51-9 differently. You can refer to the following data:
1. Useful in the study of tyrosine-phosphorylation, which has been linked with the malignant transformation of cells by some RNA tumour viruses.
2. O-Phospho-L-tyrosine is used in the study of tyrosine-phosphorylation, which has been linked to the malignant transformation of cells by various RNA tumor viruses. Plays a role in signal transduction.
Definition
ChEBI: A non-proteinogenic L-alpha-amino acid that is L-tyrosine phosphorylated at the phenolic hydroxy group.
Purification Methods
Purify it by recrystallisation from H2O or H2O/EtOH. [Levene & Schormüller J Biol Chem 100 583 1933, Posternak & Graff Helv Chim Acta 28 1258 1945, Beilstein 14 III 1510.]
Check Digit Verification of cas no
The CAS Registry Mumber 21820-51-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,2 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21820-51:
(7*2)+(6*1)+(5*8)+(4*2)+(3*0)+(2*5)+(1*1)=79
79 % 10 = 9
So 21820-51-9 is a valid CAS Registry Number.
