Check Digit Verification of cas no
The CAS Registry Mumber 54598-91-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,5,9 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 54598-91:
(7*5)+(6*4)+(5*5)+(4*9)+(3*8)+(2*9)+(1*1)=163
163 % 10 = 3
So 54598-91-3 is a valid CAS Registry Number.

Quinones,10. - Synthesis of 3-tert-Butyl-5,8-dimethyl-1,10-anthraquinone
Setiabudi, Frans,Boldt, Peter
, p. 1272 - 1279 (2007/10/02)
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).
