108158-11-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108158-11-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,1,5 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 108158-11:
(8*1)+(7*0)+(6*8)+(5*1)+(4*5)+(3*8)+(2*1)+(1*1)=108
108 % 10 = 8
So 108158-11-8 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.
