Phosphorane, (2-bromo-9H-fluoren-9-ylidene)triphenyl-, is a phosphorus-containing organic compound with the chemical formula C31H22BrP. It is a colorless solid that is soluble in organic solvents. Phosphorane, (2-bromo-9H-fluoren-9-ylidene)triphenyl- is a phosphorus ylid, which is a type of phosphorus-stabilized carbanion. It is used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the Wittig reaction. The presence of the 2-bromo-9H-fluoren-9-ylidene group provides stability to the ylid, making it a useful intermediate in the synthesis of various organic compounds. Due to its reactivity, it should be handled with care, and safety precautions should be taken during its use and storage.

7293-76-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7293-76-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,9 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7293-76:
(6*7)+(5*2)+(4*9)+(3*3)+(2*7)+(1*6)=117
117 % 10 = 7
So 7293-76-7 is a valid CAS Registry Number.
