Uses
1,4,5,8-Tetrachloroanthraquinone is an intermediate used to prepare trianthrimides as potential high-performance pigments. It can also be used to synthesize γ-aminobutyric acid analogs as novel potent GABA-AT (γ-aminobutyrate aminotransferase) inhibitors.
Check Digit Verification of cas no
The CAS Registry Mumber 81-58-3 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81-58:
(4*8)+(3*1)+(2*5)+(1*8)=53
53 % 10 = 3
So 81-58-3 is a valid CAS Registry Number.

Arylation of chloroanthraquinones by surprisingly facile Suzuki-Miyaura cross-coupling reactions
Thiemann, Thies,Tanaka, Yasuko,Iniesta, Jesus,Varghese, H. Tresa,Pannicker, C. Yohannan
experimental part, p. 732 - 736 (2010/03/24)
Chloroanthraquinones were found to undergo facile Suzuki-cross coupling with substituted phenyl boronic acids using a commercial catalyst Pd(PPh 3)4 and with Pd(PPh3)4 prepared in situ from Pd(PPh3)2Cl2 and PPh3.
