Check Digit Verification of cas no

The CAS Registry Mumber 204523-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,5,2 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 204523-65:
(8*2)+(7*0)+(6*4)+(5*5)+(4*2)+(3*3)+(2*6)+(1*5)=99
99 % 10 = 9
So 204523-65-9 is a valid CAS Registry Number.

Remarkable tethering effect on DNA cleavage of propargylic sulfone conjugates with intercalating moieties

Dai, Wei-Min,Li, Quan,Fong, Kin Chiu,Chow, Chun Wo,Zhou, Ling,Hamaguchi, Wataru,Nishimoto, Sei-Ichi

, p. 169 - 174 (1998)

A number of novel propargylic sulfone conjugates 3 and 4 with intercalating moieties were synthesized and evaluated for DNA cleavage activity through nucleic base alkylation. A remarkable enhancement in DNA cleaving potency was observed with those conjugates 3 possessing a suitable spacer, a right attachment point at the aromatic ring, and a good intercalator.
