944828-45-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 944828-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,8,2 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 944828-45:
(8*9)+(7*4)+(6*4)+(5*8)+(4*2)+(3*8)+(2*4)+(1*5)=209
209 % 10 = 9
So 944828-45-9 is a valid CAS Registry Number.

An unusual class of 5,6,7-trioxygenated dihydroflavonols (3a-e and 4a-j) were designed and prepared. Their antioxidative properties were assessed by examining their capacities in several in vitro models, including superoxide anion and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, rat liver homogenate lipid peroxidation inhibition, PC12 cells protection from oxidative damage, and xanthine oxidase inhibition. These dihydroflavonols displayed positive quenching abilities towards O2{radical dot} - and DPPH free radicals, in which the majority exhibited superior antioxidant properties to Vitamin C. cis-Configurated compound (±)-3e demonstrated remarkable inhibition to LPO with an IC50 value of 1.9 ± 0.3 μM, which was apparently stronger than that of quercetin (IC50 = 6.0 ± 0.4 μM). trans-Configurated dihydroflavonol (±)-4h exhibited significant protective effect on PC12 cells against oxidative damage with an EC50 value of 41.5 ± 5.3 μM, more effective compared to that of quercetin (EC50 = 81.8 ± 8.7 μM). The 6-OH-5,7-dimethoxy analogue (±)-3d showed significant inhibition of xanthine oxidase with an IC50 value of 16.0 ± 0.8 μM, which is superior to that of allopurinol (IC50 = 23.5 ± 2.0 μM). In addition to the hypothesized action mechanism of the bio-active compounds, 3D modeling was used to analyze the relationship between the minimized-energy structures and antioxidant activities.
