112515-44-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112515-44-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,5,1 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 112515-44:
(8*1)+(7*1)+(6*2)+(5*5)+(4*1)+(3*5)+(2*4)+(1*4)=83
83 % 10 = 3
So 112515-44-3 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.
