Check Digit Verification of cas no

The CAS Registry Mumber 143632-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,6,3 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143632-19:
(8*1)+(7*4)+(6*3)+(5*6)+(4*3)+(3*2)+(2*1)+(1*9)=113
113 % 10 = 3
So 143632-19-3 is a valid CAS Registry Number.

Recognition of all four base pairs of double-helical DNA by triple-helix formation: Design of nonnatural deoxyribonucleosides for pyrimidine-purine base pair binding

Griffin, Linda C.,Kiessling, Laura L.,Beal, Peter A.,Gillespie, Paul,Dervan, Peter B.

, p. 7976 - 7982 (2007/10/02)

The sequence-specific recognition of double-helical DNA by oligonuclcotide-directed triple-helix formation is limited mostly to purine tracts. Design leads that could expand the recognition code to all four Watson-Crick base pairs would provide one step t
