26590-20-5 Usage
Chemical Properties
light yellow liquid,colorless liquidUses
AC 220 is a uniquely potent and selective inhibitor of FLT3 for the treatment of acute myeloid leukemia (AML).Definition
ChEBI: A cyclic dicarboxylic anhydride that is the cyclic anhydride of methyltetrahydrophthalic acid.Check Digit Verification of cas no
The CAS Registry Mumber 26590-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,5,9 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.Calculate Digit Verification of CAS Registry Number 26590-20:
(7*2)+(6*6)+(5*5)+(4*9)+(3*0)+(2*2)+(1*0)=115
115 % 10 = 5
So 26590-20-5 is a valid CAS Registry Number.
