Cyclopentane, ethenylidene-, also known as 1-cyclopentene or cyclopentene, is a cyclic hydrocarbon compound with the molecular formula C5H8. It is an important intermediate in the petrochemical industry and is used in the production of various chemicals, such as adipic acid, caprolactam, and cyclopentanone. Cyclopentene is a colorless liquid with a pungent odor and is insoluble in water but soluble in organic solvents. It is a reactive compound due to the presence of a double bond, which allows it to undergo various chemical reactions, such as hydrogenation, halogenation, and oxidation. Cyclopentene is also used as a monomer in the production of polymers and copolymers, and it has applications in the synthesis of pharmaceuticals, fragrances, and agrochemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 7439-00-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,3 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7439-00:
(6*7)+(5*4)+(4*3)+(3*9)+(2*0)+(1*0)=101
101 % 10 = 1
So 7439-00-1 is a valid CAS Registry Number.
