Check Digit Verification of cas no

The CAS Registry Mumber 1423617-08-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,3,6,1 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1423617-08:
(9*1)+(8*4)+(7*2)+(6*3)+(5*6)+(4*1)+(3*7)+(2*0)+(1*8)=136
136 % 10 = 6
So 1423617-08-6 is a valid CAS Registry Number.

Nickel-catalyzed decarbonylative polymerization of 5-alkynylphthalimides: A new methodology for the preparation of polyheterocycles

Takeuchi, Makoto,Kurahashi, Takuya,Matsubara, Seijiro

, p. 1566 - 1568 (2013/01/15)

A nickel-catalyzed decarbonylative cycloaddition was developed, in which 5-alkynylphthalimides reacted to afford a new type of polyisoquinolone. It was demonstrated for the first time that decarbonylative cycloaddition can be an elementary process of polycondensation for the preparation of heterocyclic polymers.
