39581-98-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 39581-98-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,5,8 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 39581-98:
(7*3)+(6*9)+(5*5)+(4*8)+(3*1)+(2*9)+(1*8)=161
161 % 10 = 1
So 39581-98-1 is a valid CAS Registry Number.

Starting from 7-hydroxyisoflavones, we developed a new class of fluorescent scaffolds, 3-alkyl-6-methoxy-7-hydroxy-chromones (AMHCs, MW ~ 205.19, λab ~ 350 nm, λem ~ 450 nm) via a trial and error process. AMHCs have the advantages of being a small molecular moiety, having strong fluorescence in basic buffers, reasonable solubility and stability, non-toxicity, and are conveniently linked to pharmacophores. AMHCs were successfully used in fluorescence microscopy imaging of cells and tissues. This journal is
