145121-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145121-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,1,2 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 145121-23:
(8*1)+(7*4)+(6*5)+(5*1)+(4*2)+(3*1)+(2*2)+(1*3)=89
89 % 10 = 9
So 145121-23-9 is a valid CAS Registry Number.

Palladium-catalysed intramolecular cyclisation of 7-halo-N-allyl-indoles
Black,Keller,Kumar
, p. 7601 - 7608 (2007/10/02)
The N-allyl substituted-7-bromo-indoles (4-9) and the N-propargyl-7-bromo-indole(10) were prepared from the 7-bromo-indole (3). Compounds (4) and (7) undergo palladium-catalysed cyclisation to the pyrroloquinolines (11) and (13). Similar reactions of comp
