Check Digit Verification of cas no

The CAS Registry Mumber 1427698-07-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,7,6,9 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1427698-07:
(9*1)+(8*4)+(7*2)+(6*7)+(5*6)+(4*9)+(3*8)+(2*0)+(1*7)=194
194 % 10 = 4
So 1427698-07-4 is a valid CAS Registry Number.

Highly efficient benzannulation of poly(phenylene ethynylene)s

Arslan, Hasan,Saathoff, Jonathan D.,Bunck, David N.,Clancy, Paulette,Dichtel, William R.

, p. 12051 - 12054 (2013/01/16)

Put a ring on it: Sterically congested polyarylenes can be synthesized by benzannulation reactions at each C≡C bond of a poly(phenylene ethynylene) (see picture), one of the most easily synthesized and versatile classes of conjugated polymers. The benzannulation reaction is highly specific and efficient, as determined by an isotopic labeling study and several complementary spectroscopic methods. Copyright
