Calculate Digit Verification of CAS Registry Number 1215719-81:
(9*1)+(8*2)+(7*1)+(6*5)+(5*7)+(4*1)+(3*9)+(2*8)+(1*1)=145
145 % 10 = 5
So 1215719-81-5 is a valid CAS Registry Number.

Novel rhodamine dyes via suzuki coupling of xanthone triflates with arylboroxins

Calitree, Brandon D.,Detty, Michael R.

, p. 89 - 92 (2010)

Novel rhodamine dyes were prepared from xanthone precursors in a 'one-pot' procedure via reaction of the xanthone with trifluoromethanesulfonic anhydride followed by Pd-mediated Suzuki coupling between the xanthone triflate and an arylboroxin. Rhodamines with 9-(3- or 4-carboxyphenyl) and 9-(3-nitrophenyl) substituents were prepared by this procedure. The procedure also works well with thio- and selenoxanthones, but not with telluroxanthones. Georg Thieme verlag Stuttgart.
