Synthesis
111 g (416 mmol) of 6’-bromo-2’-fluorobiphenyl-2-ol are dissolved in 21 of SeccoSolv DMF (max 0.003% of H20) and cooled to 5°C. 20 g (449 mmol) of sodium hydride (60% suspension in paraffin oil) are added in portions tothis solution, and the mixture is stirred for a further 20 mm. after the addition is complete and then heated at 100°C for 45 mm. After cooling, 500 ml of ethanol are slowly added to the mixture, which is then evaporated to dryness in a rotary evaporator and purified by chromatography. Yield: 90 g (367 mmol), 88.5% of theory.
Check Digit Verification of cas no
The CAS Registry Mumber 50548-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,5,4 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 50548-45:
(7*5)+(6*0)+(5*5)+(4*4)+(3*8)+(2*4)+(1*5)=113
113 % 10 = 3
So 50548-45-3 is a valid CAS Registry Number.
