134420-43-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134420-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,4,2 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134420-43:
(8*1)+(7*3)+(6*4)+(5*4)+(4*2)+(3*0)+(2*4)+(1*3)=92
92 % 10 = 2
So 134420-43-2 is a valid CAS Registry Number.

Convenient access to bis-indole alkaloids. Application to the synthesis of?topsentins
Mal, Sajal K.,Bohé, Luis,Achab, Sa?d
, p. 5904 - 5914 (2008/12/20)
Topsentins and related bis-indole alkaloids may be efficiently synthesized through an addition/oxidation sequence leading to 2-(3-indolylcarbonyl)-imidazole derivatives followed by a Pd-catalyzed heteroarylation with the appropriate 3-stannylindoles.
