7156-31-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7156-31-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,5 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7156-31:
(6*7)+(5*1)+(4*5)+(3*6)+(2*3)+(1*1)=92
92 % 10 = 2
So 7156-31-2 is a valid CAS Registry Number.

The Fischer indolisation reaction and the synthesis of dihydroindenoindoles

Brown, David W.,Mahon, Mary F.,Ninan, Aleyamma,Sainsbury, Malcolm,Shertzer, Howard G.

, p. 8919 - 8932 (2007/10/02)

The Fischer reaction between indanones and certain alkoxyarylhydrazines fails; the indanones are returned unreacted and the arylhydrazines are converted into the corresponding alkoxy-2-chloroarylamines and other products.A new N-amination route to arylhydrazines from the arylamines has been developed and it has been demonstrated that problems with the indolisation of alkoxyarylhydrazones can be circumvented by ring closures of their O-tosylated analogues.Some results using the Lepke synthesis of indoles are recorded.
