1H-Phosphole, 1-[2-(9H-fluoren-9-ylidene)-3-methoxy-1-(methoxycarbonyl)-3-oxopropylidene]-1,1-dihydro-1,2,5-triphenyl- is a complex organic compound characterized by a phosphole ring system. This molecule features a 1H-phosphole core, which is a five-membered ring containing one phosphorus atom and four carbon atoms. The compound is further defined by a 1,1-dihydro-1,2,5-triphenyl substitution pattern, indicating the presence of three phenyl groups attached to the phosphole ring, with one hydrogen atom added to the ring to form a dihydro derivative. Additionally, the molecule contains a 2-(9H-fluoren-9-ylidene)-3-methoxy-1-(methoxycarbonyl)-3-oxopropylidene moiety, which adds complexity to the structure with its fluorenyl group, methoxy and methoxycarbonyl substituents, and an oxopropylidene bridge. This intricate arrangement of functional groups and aromatic rings contributes to the compound's unique chemical properties and potential applications in various fields, such as materials science and pharmaceuticals.

Check Digit Verification of cas no

The CAS Registry Mumber 89997-09-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,9 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89997-09:
(7*8)+(6*9)+(5*9)+(4*9)+(3*7)+(2*0)+(1*9)=221
221 % 10 = 1
So 89997-09-1 is a valid CAS Registry Number.
