Check Digit Verification of cas no

The CAS Registry Mumber 209347-44-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,3,4 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 209347-44:
134 % 10 = 4

10-Benzoyl-1,8-dihydroxy-9(10H)-anthracenones: Synthesis and biological properties

Mueller, Klaus,Altmann, Reinhold,Prinz, Helge

, p. 209 - 214 (1998)

The synthesis and biological properties of 10-benzoyl-1,8-dihydroxy-9(10H)-anthracenones are described. The compounds were evaluated for their ability to inhibit the growth of the human keratinocyte cell line HaCaT and the 5-lipoxygenase enzyme in bovine polymorphonuclear leukocytes. In addition, generation of hydroxyl radicals was determined as measured by deoxyribose degradation. The results obtained with the new compounds show that substitution with a 4-hydroxy (4f) or a 4-benzyloxy group (4i) at the phenyl ring of the C-10 substituent resulted in potent antiproliferative agents. No correlation was found between hydroxyl-radical formation and the 5-LO inhibitory or antiproliferative action of the compounds.
