Check Digit Verification of cas no

The CAS Registry Mumber 1219101-90-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,1,0 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1219101-90:
(9*1)+(8*2)+(7*1)+(6*9)+(5*1)+(4*0)+(3*1)+(2*9)+(1*0)=112
112 % 10 = 2
So 1219101-90-2 is a valid CAS Registry Number.

Toolbox for regioselective lithiations of furo[2,3-c]pyridine

Chartoire, Anthony,Comoy, Corinne,Fort, Yves

experimental part, p. 2227 - 2235 (2010/06/15)

Chemical Reaction Reprentation A detailed procedure for successive regioselective lithiations of furo[2,3-c]pyridine is described by using n-BuLi and the [n-BuLi/LiDMAE] Superbase. Several polysubstituted furo[2,3-c]pyridines have been efficiently synthesized and some of them were engaged in Pd- or Ni-catalyzed coupling reactions leading to 2,2'- or 7,7'-bifuro[2,3-c]pyridine ligands.
