1821-19-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1821-19-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,2 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1821-19:
(6*1)+(5*8)+(4*2)+(3*1)+(2*1)+(1*9)=68
68 % 10 = 8
So 1821-19-8 is a valid CAS Registry Number.

Regio and diastereoselective synthesis of functionalized 2,3-dihydrofuro[3,2-c]coumarins via a one-pot three-component reaction

Altieri, Elisa,Cordaro, Massimiliano,Grassi, Giovanni,Risitano, Francesco,Scala, Angela

, p. 9493 - 9496 (2010)

An efficient and straightforward synthesis of furo[3,2-c]coumarins via the one-pot three-component condensation of aromatic aldehydes, 4-hydroxycoumarin and α-chloroketones in refluxing n-propanol is described. Pyridine or a mixture of AcOH and AcONH4 was used as a basic catalyst.

Synthesis, photophysical properties, chemo-sensing ability and computational studies of biscoumarin derivatives
