(8*2)+(7*9)+(6*0)+(5*8)+(4*2)+(3*0)+(2*4)+(1*4)=139
139 % 10 = 9
So 290820-44-9 is a valid CAS Registry Number.

A new affinity ligand for the isolation of a single 'feruloyl esterase' (FAE-III) from Aspergillus niger

Zhao, Yongxin,Sinnott, Michael L.

, p. 917 - 924 (2007/10/03)

8-Aminooctyl 5'-S-coniferyl-5'-deoxy-thio-α-L-arabinofuranoside has been synthesised and shown to be a selective affinity ligand for the feruloyl esterase III of Aspergillus niger. The hydrolyses of methyl 5-O-coumaroyl, feruloyl, or sinapoyl α-L-arabinofuranosides by this enzyme proceed at comparable rates. (C) 2000 Elsevier Science Ltd.
