Check Digit Verification of cas no

The CAS Registry Mumber 143667-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,6,6 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143667-89:
(8*1)+(7*4)+(6*3)+(5*6)+(4*6)+(3*7)+(2*8)+(1*9)=154
154 % 10 = 4
So 143667-89-4 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
