66124-40-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66124-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,1,2 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 66124-40:
(7*6)+(6*6)+(5*1)+(4*2)+(3*4)+(2*4)+(1*0)=111
111 % 10 = 1
So 66124-40-1 is a valid CAS Registry Number.

Benzimidazolium Salts by Nucleophilic Aromatic Substitution
Wolff, Hans-Michael,Hartke, Klaus
, p. 266 - 279 (2007/10/02)
Condensation of the N,N'-dimethylbenzamidines 5 or their lithium salts 6 with o-nitrophenyl substituted aryl fluorides leads to the benzamidines 7.These cyclise on heating up to 100-150 deg C by nucleophilic aromatic substitution to form the benzimidazoli
