2-((E)-2-Phenylethenyl)-4-methylenetetrahydrofuran is a complex organic compound characterized by a unique molecular structure. It features a tetrahydrofuran ring, which is a saturated heterocyclic compound with an oxygen atom in the ring, and a phenylethenyl group attached to the 2-position. The "E" in the name indicates that the double bond between the phenyl group and the ethylenic carbon is in the E-configuration, meaning that the highest priority substituents are on opposite sides of the double bond. 2-((E)-2-Phenylethenyl)-4-methylenetetrahydrofuran is significant in organic chemistry due to its potential applications in the synthesis of various pharmaceuticals and fragrances, as well as its role as an intermediate in the production of other organic compounds. Its specific properties, such as reactivity and stability, are influenced by the arrangement of its atoms and the presence of the double bond, making it a subject of interest for further chemical research and development.

Check Digit Verification of cas no

The CAS Registry Mumber 99583-46-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,5,8 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 99583-46:
(7*9)+(6*9)+(5*5)+(4*8)+(3*3)+(2*4)+(1*6)=197
197 % 10 = 7
So 99583-46-7 is a valid CAS Registry Number.
