1H-fluorene, also known as fluorene or 9H-fluorene, is an organic compound with the molecular formula C13H10. It is a polycyclic aromatic hydrocarbon (PAH) consisting of a benzene ring fused to a cyclohexene ring. 1H-fluorene is a colorless, crystalline solid with a melting point of 115-116°C and a boiling point of 295-300°C. It is insoluble in water but soluble in organic solvents such as ethanol and ether. 1H-fluorene is used as a precursor in the synthesis of various chemicals, including pharmaceuticals, dyes, and polymers. Due to its potential environmental and health risks, 1H-fluorene is classified as a hazardous substance and is subject to strict regulations in many countries.

244-36-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 244-36-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,4 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 244-36:
(5*2)+(4*4)+(3*4)+(2*3)+(1*6)=50
50 % 10 = 0
So 244-36-0 is a valid CAS Registry Number.
