117124-89-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117124-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,1,2 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 117124-89:
(8*1)+(7*1)+(6*7)+(5*1)+(4*2)+(3*4)+(2*8)+(1*9)=107
107 % 10 = 7
So 117124-89-7 is a valid CAS Registry Number.

New Benzimidazole Synthesis
Benincori, T.,Sannicolo, F.
, p. 1029 - 1033 (2007/10/02)
Thermal or acid catalyzed cyclization of several N-(N-arylbenzimidoyl)-1,4-benzoquinoneimines 2 affords 1-aryl-6-hydroxy-2-phenylbenzimidazoles 3 in fairly good yields.Structural proofs and kinetic support for the reaction mechanism are given.
