Check Digit Verification of cas no
The CAS Registry Mumber 868944-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,8,9,4 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 868944-72:
(8*8)+(7*6)+(6*8)+(5*9)+(4*4)+(3*4)+(2*7)+(1*2)=243
243 % 10 = 3
So 868944-72-3 is a valid CAS Registry Number.

Synthesis of azaphenanthridines via anionic ring closure
Hansen, Henriette M.,Lysén, Morten,Begtrup, Mikael,Kristensen, Jesper L.
, p. 9955 - 9960 (2007/10/03)
A new and convergent synthesis of azaphenanthridines via an anionic ring closure is reported. Ortho-lithiation/in situ borylation of cyanopyridines produces the corresponding cyanopyridylboronic esters, which undergo a Suzuki-Miyaura cross-coupling to giv
