94540-85-9 Usage
General Description
2-Phenanthrenecarboxylic acid ethyl ester, also known as ethyl 2-phenanthrenecarboxylate, is an organic compound that belongs to the class of esters. It is derived from phenanthrene, a polycyclic aromatic hydrocarbon found in coal tar and crude oil. This chemical is commonly used in the laboratory as a reagent and intermediate for the synthesis of various organic compounds. It has also been studied for its potential pharmaceutical properties, including its anti-inflammatory and anti-tumor activities. 2-Phenanthrenecarboxylic acid ethyl ester is a colorless to light yellow liquid with a faint, sweet odor, and it is soluble in organic solvents such as ethanol and acetone. It is important to handle this chemical with care, as it can be harmful if ingested, inhaled, or absorbed through the skin, and it may cause irritation to the eyes, skin, and respiratory system.
Check Digit Verification of cas no
The CAS Registry Mumber 94540-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,5,4 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 94540-85:
(7*9)+(6*4)+(5*5)+(4*4)+(3*0)+(2*8)+(1*5)=149
149 % 10 = 9
So 94540-85-9 is a valid CAS Registry Number.

Diene-yne cyclisation reactions of 1-ethynyl-2-vinyl-3,4- dihydronaphthalenes and 1-ethynyl-2-vinylnaphthalenes
Watanabe, Masataka,Shiine, Kodai,Ldeta, Keiko,Matsumoto, Taisuke,Thiemann, Thies
experimental part, p. 669 - 678 (2009/09/06)
The reaction of 1-ethynyl-2-vinyl-3,4-dihydronaphthalenes and 1-ethynyl-2-vinylnaphthalenes over RuCI2(p-cymene) PPh3 leads to 9,10-dihydrophenanthrenes and phenanthrenes in those cases where the ethynyl group in the substrates carries a terminal proton. When 1-phenylethynyl-2-vinyl-3,4-dihydronaphthalenes or 1-phenylethynyl-2- vinylnaphthalenes are reacted over Pt(PPh3)4, 1-methylene-1H-benz[e]-4,5-dihydroindenes and 1-methylene-1H-benz[e]indenes are formed.
