Triphenyl-telluronium fluoride is a chemical compound with the formula (C6H5)3TeF. It is a derivative of tellurium, a metalloid element, where three phenyl groups (C6H5) are attached to a central tellurium atom, and a fluoride ion (F-) is bonded to the tellurium. triphenyl-telluronium; fluoride is of interest in organometallic chemistry and has potential applications in the synthesis of various organotellurium compounds. Triphenyl-telluronium fluoride is typically synthesized by reacting triphenyltellurane with a fluorinating agent, such as hydrogen fluoride or antimony pentafluoride. It is a colorless solid that is sensitive to air and moisture, and it is often used as a reagent in organic synthesis to introduce tellurium-containing groups into organic molecules.
The CAS Registry Mumber 437-10-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 7 respectively; the second part has 2 digits, 1 and 0 respectively. Calculate Digit Verification of CAS Registry Number 437-10: (5*4)+(4*3)+(3*7)+(2*1)+(1*0)=55 55 % 10 = 5 So 437-10-5 is a valid CAS Registry Number.
