6730-96-7 Usage
General Description
2,2,4,4,5,5,7,7-octamethyl-3,6-dioxa-2,7-disilaoctane is a silicone-based chemical compound with the chemical formula C12H36O2Si2. It is also known as octamethylcyclotetrasiloxane and is a colorless and odorless liquid at room temperature. 2,2,4,4,5,5,7,7-octamethyl-3,6-dioxa-2,7-disilaoctane is commonly used as a solvent, lubricant, and as a precursor for the production of silicone polymers and resins. It is also used in the manufacture of personal care products, such as cosmetics and hair care products, as well as in the electronics industry for the production of electronic components and devices. Additionally, it is known to have low toxicity and is considered to be relatively safe for use in various industrial and consumer applications.
Check Digit Verification of cas no
The CAS Registry Mumber 6730-96-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,3 and 0 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6730-96:
(6*6)+(5*7)+(4*3)+(3*0)+(2*9)+(1*6)=107
107 % 10 = 7
So 6730-96-7 is a valid CAS Registry Number.

The incorporation of alkoxy ligands within a range of alkoxyfluoroboranes and dialkoxyfluoroboranes results in fluoroborane reagents with attenuated Lewis acidity and increased ability to donate fluoride ion(s) when compared to boron trifluoride itself. Pinacolatoboron fluoride (pinBF), prepared in situ from BF3·OEt2 and bis(O-trimethylsilyl)pinacol, has been identified as an efficient fluoride donor which allows highly stereoselective SN1-type epoxide ring-opening (with retention of configuration) of a range of trans-β-methyl-substituted aryl epoxides to give the corresponding syn-fluorohydrins. The substrate scope of this transformation is more broad than the analogous protocol using boron trifluoride alone.
