Calculate Digit Verification of CAS Registry Number 117644-32:
(8*1)+(7*1)+(6*7)+(5*6)+(4*4)+(3*4)+(2*3)+(1*2)=123
123 % 10 = 3
So 117644-32-3 is a valid CAS Registry Number.

2H-Benzimidazoles (Isobenzimidazoles). Part 3. Thermal Isomerisation of Substituted 2H-Benzimidazoles to 1H-Benzimidazoles

Herbert, John A. L.,Iddon, Brian,Robinson, Andrew G.,Suschitzky, Hans

, p. 991 - 998 (2007/10/02)

2H-Benzimidazole-2-spirocyclohexanes (1) when heated undergo a 1,5-sigmatropic rearrangement to 2,3-disubstituted 1H-benzimidazoles.A decided effect on the direction of this isomerisation was observed with substituents in the homodiene ring.
