33916-25-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 33916-25-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,1 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 33916-25:
(7*3)+(6*3)+(5*9)+(4*1)+(3*6)+(2*2)+(1*5)=115
115 % 10 = 5
So 33916-25-5 is a valid CAS Registry Number.

Synthesis of the antimycobacterial naphthoquinone, 7-methyljuglone and its dimer, neodiospyrin

Van Der Kooy, Frank,Meyer, J.J. Marion

, p. 60 - 61 (2007/10/03)

We report on the laboratory-scale synthesis of the antimycobacterial naphthoquinone, 7-methyljuglone (7-methyl-5-hydroxy-1,4-naphthoquinone) in a one step Friedel-Crafts acylation reaction. This compound was used to synthesize neodiospyrin, which possesses similar bioactivity.

Synthesis of Neodiospyrin and Fixation of Aryl-Quinone Linkage in Its Structure

Kumari, L. Krishna,Babu, M. Hari,Pardhasaradhi, M.

, p. 619 - 621 (2007/10/02)

The first synthesis of neodiospyrin (I) is achieved through quinone-naphthol coupling.Sodium dithionite reduction of the dialkyl ethers of I yields hemiketals (VIa and VIb).The aryl-quinone linkage in I is shown tobe 8-3'.
