117125-16-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117125-16-3 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 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 117125-16:
(8*1)+(7*1)+(6*7)+(5*1)+(4*2)+(3*5)+(2*1)+(1*6)=93
93 % 10 = 3
So 117125-16-3 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.
