Triphenyl-{5-[1-[5-(triphenyl-λ⁵-phosphanylidene)-cyclopenta-1,3-dienyl]-meth-(E)-ylidene]-cyclopenta-1,3-dienyl}-phosphonium; iodide is a complex organic compound consisting of a phosphonium cation and an iodide anion. The cation features a central phosphorus atom bonded to three phenyl groups and a cyclopenta-1,3-dienyl group, which is further connected to another cyclopenta-1,3-dienyl group through a meth-(E)-ylidene bridge. This structure is characterized by its unique arrangement of carbon and phosphorus atoms, forming a stable, charge-separated ion pair with the iodide anion. Triphenyl-{5-[1-[5-(triphenyl-λ⁵-phosphanylidene)-cyclopenta-1,3-dienyl]-meth-(E)-ylidene]-cyclopenta-1,3-dienyl}-phosphonium; iodide is of interest in the field of organophosphorus chemistry and may have potential applications in various chemical reactions and materials science.

Check Digit Verification of cas no

The CAS Registry Mumber 1908-52-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,0 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1908-52:
(6*1)+(5*9)+(4*0)+(3*8)+(2*5)+(1*2)=87
87 % 10 = 7
So 1908-52-7 is a valid CAS Registry Number.
