98478-22-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98478-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,7 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 98478-22:
(7*9)+(6*8)+(5*4)+(4*7)+(3*8)+(2*2)+(1*2)=189
189 % 10 = 9
So 98478-22-9 is a valid CAS Registry Number.

The title compound 3f is a novel isolable 1,10-anthraquinone which is stabilized only by alkyl groups.Despite of the shielding of the meso position 3f reacts very fast with water and oxygen to give 3-tert-butyl-1-hydroxy-5,8-dimethyl-9,10-anthraquinone (4f).
