Check Digit Verification of cas no

The CAS Registry Mumber 543683-71-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,3,6,8 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 543683-71:
(8*5)+(7*4)+(6*3)+(5*6)+(4*8)+(3*3)+(2*7)+(1*1)=172
172 % 10 = 2
So 543683-71-2 is a valid CAS Registry Number.

A m-benzyne to o-benzyne conversion through a 1,2-shift of a phenyl group

Blake, Michael E.,Bartlett, Kevin L.,Jones Jr., Maitland

, p. 6485 - 6490 (2003)

Pyrolysis of two differently labeled versions of 3-phenylphthalic anhydride shows that a m-benzyne can form the related o-benzyne through shift of a phenyl group. The highest energy point in the process is the transition structure for a reverse carbon-hyd
