66291-32-5 Usage
General Description
3,9-DIMETHYLPHENANTHRENE is a polycyclic aromatic hydrocarbon (PAH) compound that consists of three fused benzene rings. It is a colorless to light yellow solid that is not soluble in water but is soluble in organic solvents. 3,9-DIMETHYLPHENANTHRENE is primarily used as a research chemical and is not widely used in industrial applications. It is known to be a potent inducer of the enzyme cytochrome P450, which is involved in the metabolism of various drugs and carcinogens in the liver. Due to its chemical structure and potential health effects, 3,9-DIMETHYLPHENANTHRENE is considered to be a hazardous compound and should be handled with caution to minimize exposure and potential health risks.
Check Digit Verification of cas no
The CAS Registry Mumber 66291-32-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,2,9 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 66291-32:
(7*6)+(6*6)+(5*2)+(4*9)+(3*1)+(2*3)+(1*2)=135
135 % 10 = 5
So 66291-32-5 is a valid CAS Registry Number.

Br?nsted Acid-Catalyzed Carbonyl-Olefin Metathesis: Synthesis of Phenanthrenes via Phosphomolybdic Acid as a Catalyst

Compared with the impressive achievements of catalytic carbonyl-olefin metathesis (CCOM) mediated by Lewis acid catalysts, exploration of the CCOM through Br?nsted acid-catalyzed approaches remains quite challenging. Herein, we disclose a synthetic protocol for the construction of a valuable polycycle scaffold through the CCOM with the inexpensive, nontoxic phosphomolybdic acid as a catalyst. The current annulations could realize carbonyl-olefin, carbonyl-alcohol, and acetal-alcohol in situ CCOM reactions and feature mild reaction conditions, simple manipulation, and scalability, making this strategy a promising alternative to the Lewis acid-catalyzed COM reaction.
