Check Digit Verification of cas no
The CAS Registry Mumber 139035-98-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,3 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139035-98:
(8*1)+(7*3)+(6*9)+(5*0)+(4*3)+(3*5)+(2*9)+(1*8)=136
136 % 10 = 6
So 139035-98-6 is a valid CAS Registry Number.

Synthesis and Antifungal Activity of 5,6-Dihydro-3-methyl-1,4-dioxin-2-carboxamides
Dekeyser, Mark A.,Davis, Robert A.
, p. 2827 - 2829 (2007/10/03)
Seven N-aryl-5,6-dihydro-3-methyl-1,4-dioxin-2-carboxamides were prepared as potential fungicides. The fungicidal activity of the dioxincarboxamides was evaluated against bean rust, a major disease of cereal crops. Structure-activity relationships for the screened compounds are discussed. The fungicidal activity of the dioxincarboxamides is correlated with that of the structurally similar commercial fungicide, carboxin.
