116509-24-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116509-24-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,5,0 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 116509-24:
(8*1)+(7*1)+(6*6)+(5*5)+(4*0)+(3*9)+(2*2)+(1*4)=111
111 % 10 = 1
So 116509-24-1 is a valid CAS Registry Number.

Synthesis of 2H-pyrroles by treatment of pyrrolidines with DDQ
Cheruku, Srinivasa R.,Padmanilayam, Maniyan P.,Vennerstrom, Jonathan L.
, p. 3701 - 3703 (2003)
A mild and efficient synthesis of 2,2-dialkyl-3,5-diaryl-2H-pyrroles is described. Treatment of 2,2-dialkyl-3,5-diarylpyrrolidines with DDQ in dioxane for 12-24 h at rt afforded the corresponding 2H-pyrroles in 55-81% overall yields.
