Check Digit Verification of cas no

The CAS Registry Mumber 1173986-34-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,9,8 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1173986-34:
(9*1)+(8*1)+(7*7)+(6*3)+(5*9)+(4*8)+(3*6)+(2*3)+(1*4)=189
189 % 10 = 9
So 1173986-34-9 is a valid CAS Registry Number.

The antioxidant activity of butane-type lignans was evaluated. Secoisolariciresinol (SECO) and dihydroguaiaretic acid (DGA) showed higher radical scavenging activity than that of 7,7′-dioxodihydroguaiaretic acid (ODGA). SECO and DGA inhibited the oxidation of unsaturated fatty acid. Both enantiomers of DGA were also lipoxygenase inhibitors, but neither enantiomer of SECO inhibited the lipoxygenase activity.
