Check Digit Verification of cas no

The CAS Registry Mumber 221297-86-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,2,9 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 221297-86:
(8*2)+(7*2)+(6*1)+(5*2)+(4*9)+(3*7)+(2*8)+(1*6)=125
125 % 10 = 5
So 221297-86-5 is a valid CAS Registry Number.

Synthesis of polyazacyclophane-intercalator conjugates for combinatorial chemistry and RNA interaction studies

Wang,An,Haly,Cook

, p. 687 - 696 (2007/10/03)

Anthraquinone and pyrene intercalators were conjugated to different positions of several polyazapyridinocyclophanes by various linkers to provide thirteen new polyazacyclophane-intercalator conjugates 1-13. These resulting conjugates contain two or three constrained secondary nitrogen atoms on the ring, which may serve as nucleophilic, coordinating or hydrogen-bonding sites for combinatorial, RNA interaction and coordination studies.
