Check Digit Verification of cas no

The CAS Registry Mumber 203261-25-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,2,6 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 203261-25:
(8*2)+(7*0)+(6*3)+(5*2)+(4*6)+(3*1)+(2*2)+(1*5)=80
80 % 10 = 0
So 203261-25-0 is a valid CAS Registry Number.

Synthesis and fungicidal activity of a series of novel aryloxylepidines

Kirby, Neil V.,Daeuble, John F.,Davis, L. Navelle,Hannum, Anna C.,Hellwig, Karin,Lawler, Lori K.,Parker, Marshall H.,Pieczko, Mary E.

, p. 844 - 851 (2001)

A series of novel (hetero)aryloxylepidine derivatives was devised as hybrid structures of the phenoxyquinoline and phenethoxyquin(az)oline fungicides. Synthesis of these targets required the development of several new routes to derivatised 4-hydroxymethylquinolines, and subsequent coupling with phenols or haloarenes. The aryloxylepidines generally showed moderate broad-spectrum fungicidal activity across several diseases of cereals. Substitution of the quinoline ring with chlorine at the 7- and/or 5-positions gave molecules with high levels of protectant activity against Erysiphe graminis f sp tritici (powdery mildew of wheat), but this did not improve the level of fungicidal activity against other diseases. In vitro activity against mitochondrial electron transport complex I (MET) derived from Ustilago maydis showed that 8-fluorolepidine analogues were moderately active at this target site, while the more fungicidally active 7- and 5,7-substituted compounds were inactive. This indicates that MET is not the primary target of these highly active powdery mildewicides.
