5209-31-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5209-31-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,0 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5209-31:
(6*5)+(5*2)+(4*0)+(3*9)+(2*3)+(1*1)=74
74 % 10 = 4
So 5209-31-4 is a valid CAS Registry Number.

A p-benzyne to m-benzyne conversion through a 1,2-shift of a phenyl group. Completion of the benzyne cascade

Polishchuk, Alexei L.,Bartlett, Kevin L.,Friedman, Lee A.,Jones Jr., Maitland

, p. 798 - 806 (2007/10/03)

Pyrolysis of 1,6-diphenylhexa-1,5-diyne-cis-3-ene at 800-1000 °C leads to a mixture of 1- and 2-phenylbiphenylene, along with triphenylene. Formation of the two biphenylenes is taken as strong evidence of the rearrangement of a p-benzyne into a m-benzyne through a shift of one of the phenyl groups. Copyright
