Uses
2-(3,4-Dimethylphenyl)-1,2-dihydro-5-methyl-3H-pyrazol-3-one, is an impurity of Eltrombopag (E508000), which is agonist of the Thrombopoietin (Tpo) receptor, used as treatment for thrombocytopenia.
Check Digit Verification of cas no
The CAS Registry Mumber 277299-70-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,7,2,9 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 277299-70:
(8*2)+(7*7)+(6*7)+(5*2)+(4*9)+(3*9)+(2*7)+(1*0)=194
194 % 10 = 4
So 277299-70-4 is a valid CAS Registry Number.
