188528-96-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188528-96-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,5,2 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 188528-96:
(8*1)+(7*8)+(6*8)+(5*5)+(4*2)+(3*8)+(2*9)+(1*6)=193
193 % 10 = 3
So 188528-96-3 is a valid CAS Registry Number.

Studies directed toward the synthesis of martinellines : One pot synthesis of pyrroloquinolone ring system
Gurjar, Mukund K.,Pal, Shashwati,Rama Rao
, p. 231 - 234 (2007/10/03)
The Pd-catalysed coupling between aryl iodides and 3-carbethoxy-4,5-dihydropyrroles has been described. With ortho-iodoanilines, tandem cyclisation leading to pyrroloquinolones present in martinellines, was observed.
