1309791-68-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1309791-68-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,7,9 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1309791-68:
(9*1)+(8*3)+(7*0)+(6*9)+(5*7)+(4*9)+(3*1)+(2*6)+(1*8)=181
181 % 10 = 1
So 1309791-68-1 is a valid CAS Registry Number.

Interaction of 3-acetoacetyl-2H-chromen-2-one with azanucleophilic reagents
Grigoryeva,Fedotova,Shkel
, p. 1509 - 1513 (2011)
The reactions of 3-acetoacetylchromen-2-one with mono- and binucleophilic reagents, under the action of microwave irradiation have been studied. It was shown that depending on the nucleophilicity of the reactant new heterocyclic systems were formed involv
