Check Digit Verification of cas no

The CAS Registry Mumber 1281964-69-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,1,9,6 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1281964-69:
(9*1)+(8*2)+(7*8)+(6*1)+(5*9)+(4*6)+(3*4)+(2*6)+(1*9)=189
189 % 10 = 9
So 1281964-69-9 is a valid CAS Registry Number.

Reactive oxygen species scavenging activities and inhibition on DNA oxidative damage of dimeric compounds from the oxidation of (-)-epigallocatechin-3-O-gallate

Qi, Xiangyang

, p. 205 - 209 (2010)

The dimeric catechins dehydrotheasinensin A (2) and theacitrin C (3) were prepared from the oxidation of (-)-epigallocatechin-3-O-gallate (EGCG, 1), and their antioxidant activity was investigated using a chemiluminescence (CL) method in vitro. Both compounds showed significant inhibitory effects on reactive oxygen species (O2-, H2O2 and ?OH) and DNA oxidative damage, with 2 being more potent than 3 and EGCG itself.
