180633-59-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 180633-59-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,6,3 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 180633-59:
(8*1)+(7*8)+(6*0)+(5*6)+(4*3)+(3*3)+(2*5)+(1*9)=134
134 % 10 = 4
So 180633-59-4 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.
