66946-99-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66946-99-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,9,4 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 66946-99:
(7*6)+(6*6)+(5*9)+(4*4)+(3*6)+(2*9)+(1*9)=184
184 % 10 = 4
So 66946-99-4 is a valid CAS Registry Number.

Colouring Matters of Australian Plants. XXIV. Haemofluorone B: New Synthetic Models and a Revised Structure

Chaffee, Alan L.,Cooke, Raymond G.,Dagley, Ian J.,Perlmutter, Patrick,Thomas, Raymond L.

, p. 587 - 598 (2007/10/02)

The occurrence of haemofluorone B in Anigozanthos rufus and Conostylis setosa has been confirmed.The revised structure 5,8,9-trihydroxy-3H-naphthoxanthen-3-one is now proposed for this pigment.Dihydroxyanigorufone has also been found in Conostylis setosa and the structure 9-(3,4-dihydroxyphenyl)-2-hydroxy-1H-phenalen-1-one has been confirmed by synthesis of the trimethyl ether.Some model arylphenalenones and naphthoxanthenones have been prepared from naphthylphenylpropanones and some unusual products have been obtained by photolysis of arylphenalenones and by the reactions of Grignard reagents with phenalenones.
