Check Digit Verification of cas no

The CAS Registry Mumber 1237786-98-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,7,7,8 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1237786-98:
(9*1)+(8*2)+(7*3)+(6*7)+(5*7)+(4*8)+(3*6)+(2*9)+(1*8)=199
199 % 10 = 9
So 1237786-98-9 is a valid CAS Registry Number.

One-pot double intramolecular homolytic aromatic substitution routes to dialicyclic ring fused imidazobenzimidazolequinones and preliminary analysis of anticancer activity

Fagan, Vincent,Bonham, Sarah,Carty, Michael P.,Aldabbagh, Fawaz

experimental part, p. 3149 - 3156 (2010/08/21)

Bu3SnH/1,1′-azobis(cyclohexanecarbonitrile) (ACN)-mediated five, six, and seven-membered double alkyl radical cyclizations onto imidazo[5,4-f]benzimidazole and imidazo[4,5-f]benzimidazole are described. The quinone derivatives evaluated show selective toxicity towards human cervical (HeLa) and prostate (DU145) cancer cell lines (with negligible toxicity towards a normal human cell line, GM00637). Only the Fremy oxidation of the 6-aminoimidazo[5,4-f]benzimidazole gave iminoquinone, which showed high specificity towards the prostate cancer cell line (DU145).
