Naphthalene, 1,2,3,4,5,6,8-heptafluoro-7-(trifluoromethyl)-, also known as perfluoronaphthalene, is a synthetic organic compound with the chemical formula C10F9. It is a halogenated derivative of naphthalene, where seven of the ten hydrogen atoms have been replaced by fluorine atoms, and one hydrogen atom has been replaced by a trifluoromethyl group. Naphthalene, 1,2,3,4,5,6,8-heptafluoro-7-(trifluoromethyl)- is characterized by its high thermal stability, chemical inertness, and low reactivity, making it useful in various industrial applications such as heat transfer fluids, refrigerants, and fire-extinguishing agents. Due to its unique properties, perfluoronaphthalene has also been studied for potential use in electronic devices and as a component in specialty materials.

737-21-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 737-21-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 737-21:
(5*7)+(4*3)+(3*7)+(2*2)+(1*1)=73
73 % 10 = 3
So 737-21-3 is a valid CAS Registry Number.
