Check Digit Verification of cas no

The CAS Registry Mumber 113250-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,2,5 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 113250-99:
(8*1)+(7*1)+(6*3)+(5*2)+(4*5)+(3*0)+(2*9)+(1*9)=90
90 % 10 = 0
So 113250-99-0 is a valid CAS Registry Number.

Studies on quinones. Part 42: Synthesis of furylquinone and hydroquinones with antiproliferative activity against human tumor cell lines

Benites, Julio,Valderrama, Jaime A.,Rivera, Felipe,Rojo, Leonel,Campos, Nair,Pedro, Madalena,Jose Nascimento, Maria Saeo

, p. 862 - 868 (2008/09/17)

The preparation of furyl-1,4-quinone and hydroquinones by reaction of 2-furaldehyde N,N-dimethylhydrazone with benzo- and naphthoquinones is reported. Access to furylnaphthoquinones from unactivated quinones requires acid-induced conditions, however oxidative coupling reactions of activated quinones proceed under neutral conditions. The in vitro cytotoxic activity of the prepared compounds against a panel of three human cancer cell lines has been studied. Most of the furyl-1,4-quinones exhibited good antiproliferative activity (GI50 = 6.5-33.5 μm) against the MCF-7, NCI-H460, and SF-268 (CNS cancer) cell lines chosen for testing.
