Check Digit Verification of cas no
The CAS Registry Mumber 33097-39-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,0,9 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 33097-39:
(7*3)+(6*3)+(5*0)+(4*9)+(3*7)+(2*3)+(1*9)=111
111 % 10 = 1
So 33097-39-1 is a valid CAS Registry Number.

Room-temperature nucleophilic aromatic fluorination: Experimental and theoretical studies
Sun, Haoran,DiMagno, Stephen G.
, p. 2720 - 2725 (2007/10/03)
(Chemical Equation Presented) Taming the reagent: The use of anhydrous tetrabutylammonium fluoride (TBAFanh) in nucleophilic aromatic substitution reactions, including variants of the selective halogen-exchange and fluorodenitration processes (see scheme), was investigated. It was shown that TBAFanh permits these reactions to be performed under surprisingly mild conditions if it is used in relatively nonpolar media.
