109541-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109541-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,5,4 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109541-22:
(8*1)+(7*0)+(6*9)+(5*5)+(4*4)+(3*1)+(2*2)+(1*2)=112
112 % 10 = 2
So 109541-22-2 is a valid CAS Registry Number.

4,5-DIPHENYLIMIDAZOLES FROM THE CYCLIZATION OF BENZIL N-ALKYLMONOHYDRAZONES
Collibee, William L.,Anselme, Jean-Pierre
, p. 655 - 662 (2007/10/02)
The thermal cyclization of monodisubstituted hydrazones (1) affords the corresponding N-substituted-4,5-diphenylimidazoles in good to excellent yields; possible mechanisms for this unusual cyclization are presented.
