Check Digit Verification of cas no
The CAS Registry Mumber 73728-78-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,7,2 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 73728-78:
(7*7)+(6*3)+(5*7)+(4*2)+(3*8)+(2*7)+(1*8)=156
156 % 10 = 6
So 73728-78-6 is a valid CAS Registry Number.

Metal-free synthesis of sterically crowded biphenyls by direct Ar-H substitution in alkyl benzenes
Dichiarante, Valentina,Fagnoni, Maurizio,Albini, Angelo
, p. 6495 - 6498 (2008/09/16)
(Chemical Equation Presented) Four's definitely a crowd: The chemoselective activation of Ar-H bonds in methylbenzenes by treatment with photogenerated phenyl cations allowed the synthesis of sterically crowded biphenyl compounds, including tetra-ortho-substituted biphenyls, by intermolecular cross-coupling (see scheme). This method is an appealing metal-free alternative to widely used transition-metal catalysis. TFE = 2,2,2-trifluoroethanol.
