73791-18-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73791-18-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,7,9 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 73791-18:
(7*7)+(6*3)+(5*7)+(4*9)+(3*1)+(2*1)+(1*8)=151
151 % 10 = 1
So 73791-18-1 is a valid CAS Registry Number.

The rhodium carbenoid route to 3-aryl-4-hydroxycoumarins: Synthesis of derrusnin
Goldoni, Luca,Cravotto, Giancarlo,Penoni, Andrea,Tollari, Stefano,Palmisano, Giovanni
, p. 927 - 930 (2007/10/03)
3-Aryl-4-hydroxycoumarins have been obtained in satisfactory yields and selectivity through a Rh(II)-mediated arylation of diazocoumarin. The utility of this approach is demonstrated by synthesis of the natural product derrusnin.
