Check Digit Verification of cas no

The CAS Registry Mumber 1316308-41-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,6,3,0 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1316308-41:
(9*1)+(8*3)+(7*1)+(6*6)+(5*3)+(4*0)+(3*8)+(2*4)+(1*1)=124
124 % 10 = 4
So 1316308-41-4 is a valid CAS Registry Number.

Synthesis of xanthones and benzophenones as inhibitors of tumor cell growth

Costa, Elisangela,Sousa, Emilia,Nazareth, Nair,Nascimento, Maria S.J.,Pinto, Madalena M.M.

, p. 487 - 493 (2010)

The synthesis of two new sulfated xanthones and two O-substituted benzophenones was carried out to evaluate for their inhibitory effect on growth of human tumor cell lines. The sulfation of 3,6-(2) and 3,4-dihydroxyxanthone (3) was accomplished using sulfur trioxide-pyridine to give, respectively, xanthone-3,6-O,O-bis(sulfate) (4) and xanthone- 3,4-O,O-bis(sulfate) (5). Treatment of 2,2',4,4'-tetrahydroxybenzophenone (6) with acetic acid and prenyl bromide furnished 2,2',4,4'- tetraacetoxybenzophenone (7) and (5-hydroxy-2,2-dimethylchroman-6-yl)(2'-hydroxy-4'-(tertpentyloxy) phenyl)methanone (8), respectively. Compounds 2-8 were tested for their effect on the in vitro growth of four representative human tumor cell lines: MCF-7 ER(+) (breast adenocarcinoma), NCI-H460 (non-small cell lung cancer), SF-268 (glioma), and A375-C5 (melanoma). Compounds 2 and 7-8 showed an inhibitory activity in the μM range.
