Check Digit Verification of cas no

The CAS Registry Mumber 1191091-31-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,1,0,9 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1191091-31:
(9*1)+(8*1)+(7*9)+(6*1)+(5*0)+(4*9)+(3*1)+(2*3)+(1*1)=132
132 % 10 = 2
So 1191091-31-2 is a valid CAS Registry Number.

Design, synthesis and evaluation of 4,5-di-substituted acridone ligands with high G-quadruplex affinity and selectivity, together with low toxicity to normal cells

Cuenca, Francisco,Moore, Michael J.B.,Johnson, Karin,Guyen, Berangere,De Cian, Anne,Neidle, Stephen

supporting information; experimental part, p. 5109 - 5113 (2010/03/31)

A series of 4,5-di-substituted acridones have been designed and synthesized. Several compounds show high affinity for telomeric G-quadruplex DNA in classical and competition FRET assays, together with low duplex DNA affinity, although they do not show activity in a telomerase assay or evidence of telomere shortening. They have low toxicity against a panel of cancer cell lines and a normal human fibroblast line, and produce potent senescence-based long-term growth arrest in the MCF7 and A549 cancer cell lines.
