Check Digit Verification of cas no
The CAS Registry Mumber 850662-59-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,6,6 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 850662-59:
(8*8)+(7*5)+(6*0)+(5*6)+(4*6)+(3*2)+(2*5)+(1*9)=178
178 % 10 = 8
So 850662-59-8 is a valid CAS Registry Number.

Potassium carbonate as a base for the N-alkylation of indole and pyrrole in ionic liquids
Jorapur, Yogesh R.,Jeong, Jae Min,Chi, Dae Yoon
, p. 2435 - 2438 (2007/10/03)
The methodology for the N-alkylation of indole and pyrrole using potassium carbonate in 1-n-butyl-3-methylimidazolium tetrafluoroborate [bmim][BF4] as the sustainable reaction media with acetonitrile as the cosolvent is described herein. Our approach provides good yields with alkyl halides as well as sulfonates as the electrophiles. Cesium carbonate was also found to be a consistent base in the N-alkylation. The proposed methodology is simple and mild with easy workup.
