Check Digit Verification of cas no

The CAS Registry Mumber 29304-89-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,3,0 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 29304-89:
(7*2)+(6*9)+(5*3)+(4*0)+(3*4)+(2*8)+(1*9)=120
120 % 10 = 0
So 29304-89-0 is a valid CAS Registry Number.

An oxidative rearrangement of 6-phenylbicyclo[3.2.0]heptan-6-ol to 1,1′-biphenyl-carbaldehydes: A mechanistic study

Ceylan, Mustafa,Findik, Esra,Secen, Hasan

, p. 559 - 568 (2008)

Acid-catalyzed rearrangement of 6-phenylbicyclo[3.2.0]heptan-6-ol gave 1,1′-biphenyl and 1,1′-biphenyl-carbaldehydes in small amounts as well as the expected rearrangement products. A detailed study of the reaction mechanism revealed that the conversion occurs via an oxidative process through the consecutive formation of cycloheptadienes, cycloheptatrienes, and 1,1′-biphenyls. The acid-catalyzed rearrangement of 6-phenylbicyclo[3.2.0] hept-2-en-6-ols gave 1- and 2-phenylcycloheptatrienes directly, from which 1,1′-biphenyl and 1,1′-biphenyl-carbaldehydes were obtained by oxidation.
