3. 4-tert-Butyl-2,6-dimethylphenylsulfur Trifluoride is a deoxofluorination reagent used in an improved method of synthesis of arylsulfur trifluorides.
General Description
4-tert-Butyl-2,6-dimethylphenylsulfur trifluoride is a thermally stable, easy-to-handle, versatile deoxofluorinating agent that also shows high stability on contact with water. It is a superior alternative to diethylaminosulfur trifluoride (DAST).
Check Digit Verification of cas no
The CAS Registry Mumber 947725-04-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,7,7,2 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 947725-04:
(8*9)+(7*4)+(6*7)+(5*7)+(4*2)+(3*5)+(2*0)+(1*4)=204
204 % 10 = 4
So 947725-04-4 is a valid CAS Registry Number.
