Check Digit Verification of cas no

The CAS Registry Mumber 518980-41-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,8,9,8 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 518980-41:
(8*5)+(7*1)+(6*8)+(5*9)+(4*8)+(3*0)+(2*4)+(1*1)=181
181 % 10 = 1
So 518980-41-1 is a valid CAS Registry Number.

Synthesis of nitrile-terminated potential molecular electronic devices

Dirk, Shawn M.,Tour, James M.

, p. 287 - 293 (2007/10/03)

Several potential molecular devices have been synthesized consisting of oligo(phenylene ethynylene) (OPE) backbones containing a terminal nitrile group alligator clip as a means of attachment to a metal surface. The synthesis of four new nitrile-containing OPEs is discussed, including an improved synthesis of an intermediate used in our prior production of OPEs containing acetate-protected thiol alligator clips.
