6994-50-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6994-50-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,9 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6994-50:
(6*6)+(5*9)+(4*9)+(3*4)+(2*5)+(1*0)=139
139 % 10 = 9
So 6994-50-9 is a valid CAS Registry Number.

Metal-free C(3)-H arylation of coumarins promoted by catalytic amounts of 5,10,15,20-tetrakis(4-diethylaminophenyl)porphyrin

Kojima, Masahiro,Oisaki, Kounosuke,Kanai, Motomu

supporting information, p. 9718 - 9721 (2016/01/09)

The metal-free C-H arylation of coumarins was achieved in the presence of catalytic amounts of 5,10,15,20-tetrakis(4-diethylaminophenyl)porphyrin. This mild and environmentally friendly Meerwein arylation provided facile access to a broad variety of 3-arylcoumarins in synthetically useful yields.
