Check Digit Verification of cas no

The CAS Registry Mumber 16297-03-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,9 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 16297-03:
(7*1)+(6*6)+(5*2)+(4*9)+(3*7)+(2*0)+(1*3)=113
113 % 10 = 3
So 16297-03-3 is a valid CAS Registry Number.

Oroxylin A analogs exhibited strong inhibitory activities against iNOS-mediated nitric oxide (NO) production

scheme or table, p. 2534 - 2535 (2012/05/05)

A number of oroxylin A analogs were prepared and evaluated for their inhibitory activities against iNOS-mediated nitric oxide (NO) production from LPS-stimulated BV2 cells. The analogs were synthesized from purchased 2′-hydroxy-4,5,6-trimethoxyacetophenone and aldehydes in 3 steps. Among the tested compounds, several analogs (3b, 3c, 3d, 3f) exhibited strong inhibitory activities. Especially, the analog with 4-nitrophenyl group (3b) showed stronger inhibitory activity (IC50 = 4.73 μM) than that of wogonin (IC50 = 7.80 μM).
