Calculate Digit Verification of CAS Registry Number 1187186-13:
(9*1)+(8*1)+(7*8)+(6*7)+(5*1)+(4*8)+(3*6)+(2*1)+(1*3)=175
175 % 10 = 5
So 1187186-13-5 is a valid CAS Registry Number.

Brominated thiophenes as precursors in the preparation of brominated and arylated anthraquinones

Thiemann, Thies,Tanaka, Yasuko,Iniesta, Jesus

experimental part, p. 1013 - 1031 (2009/10/10)

Brominated anthraquinones can be synthesized directly from bromothiophenes when these are reacted with 1,4-naphthoquinones in the presence of meta-chloroperoxybenzoic acid. The bromoanthraquinones are versatile building blocks in the preparation of arylated anthraquinones and of extended π-systems with interspersed anthraquinone units.
