Check Digit Verification of cas no

The CAS Registry Mumber 128232-62-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,3 and 2 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128232-62:
(8*1)+(7*2)+(6*8)+(5*2)+(4*3)+(3*2)+(2*6)+(1*2)=112
112 % 10 = 2
So 128232-62-2 is a valid CAS Registry Number.

Piptadenia pervillei Vatke (Fabaceae) was selected from a screening programme devoted to the search of naturally-occuring antimalarial compounds from plants of Madagascar. Bioassay-guided fractionation of the ethyl acetate extract of the leaves led to the isolation of four phenolic compounds, (+)-catechin (1), (+)-catechin 5-gallate (2), (+)-catechin 3-gallate (3) and ethyl gallate (4). Structures were determined by NMR and mass spectroscopy. Compounds 2 and 3 displayed the highest in vitro activity against the chloroquine-resistant strain FcB1 of Plasmodium falciparum with IC50 values of 1.2 μM and 1.0 μM, respectively, and no significant cytotoxicity against the human embryonic lung cells MRC-5 was measured (IC50 values > 75 μM). Five analogues (5-9) of (+)-catechin 5-gallate (2) were synthesized and evaluated for their antiplasmodial activity. Georg Thieme Verlag KG Stuttgart.
