Check Digit Verification of cas no

The CAS Registry Mumber 690258-69-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,0,2,5 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 690258-69:
(8*6)+(7*9)+(6*0)+(5*2)+(4*5)+(3*8)+(2*6)+(1*9)=186
186 % 10 = 6
So 690258-69-6 is a valid CAS Registry Number.

Synthesis of ladder polyaromatics as new molecular device candidates

Ciszek, Jacob W.,Tour, James M.

, p. 2801 - 2803 (2004)

In order to investigate one of the proposed molecular electronics switching mechanisms, we synthesized several molecules whose cores are unable to undergo conformational rotation. Preparation of these molecules, all of which are terminated with the thioac
