14736-62-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 14736-62-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,7,3 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 14736-62:
(7*1)+(6*4)+(5*7)+(4*3)+(3*6)+(2*6)+(1*2)=110
110 % 10 = 0
So 14736-62-0 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.
