577032-18-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 577032-18-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,7,7,0,3 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 577032-18:
(8*5)+(7*7)+(6*7)+(5*0)+(4*3)+(3*2)+(2*1)+(1*8)=159
159 % 10 = 9
So 577032-18-9 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 (2007/10/03)
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.
