1428552-97-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1428552-97-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,5,5 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1428552-97:
(9*1)+(8*4)+(7*2)+(6*8)+(5*5)+(4*5)+(3*2)+(2*9)+(1*7)=179
179 % 10 = 9
So 1428552-97-9 is a valid CAS Registry Number.

Synthesis of tetrasubstituted pyrroles by palladium-catalyzed cyclization of propargylic carbonates with β-enamino esters
Yoshida, Masahiro,Sugimura, Chiyuki
, p. 2082 - 2084 (2013/05/08)
The reaction of propargylic carbonates with β-enamino esters in the presence of palladium catalyst is described. Various tetrasubstituted pyrroles were regioselectively synthesized via a successive nucleophilic cyclization.
