(8*2)+(7*7)+(6*0)+(5*0)+(4*8)+(3*6)+(2*5)+(1*0)=125
125 % 10 = 5
So 270086-50-5 is a valid CAS Registry Number.

Synthesis of isothiochroman 2,2-dioxide and 1,2-benzooxathiin 2,2- dioxide gyrase B inhibitors

Peixoto, Christophe,Laurin, Patrick,Klich, Michel,Dupuis-Hamelin, Claudine,Mauvais, Pascale,Lassaigne, Patrice,Bonnefoy, Alain,Musicki, Branislav

, p. 1741 - 1745 (2000)

The design, synthesis and in vitro biological evaluation of isothiochroman 2,2-dioxide and 1,2-benzooxathiin 2,2-dioxide analogues of coumarin inhibitors of gyrase B are described. Compared to coumarin derivatives, compounds of the 1,2-benzooxathiin 2,2-dioxide series display improved inhibitory potency in negative supercoiling of relaxed DNA gyrase.
