Check Digit Verification of cas no

The CAS Registry Mumber 939026-63-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,9,0,2 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 939026-63:
(8*9)+(7*3)+(6*9)+(5*0)+(4*2)+(3*6)+(2*6)+(1*3)=188
188 % 10 = 8
So 939026-63-8 is a valid CAS Registry Number.

Synthesis of heterocyclic systems by transition-metal-catalyzed cyclization-migration reactions - A diversity-oriented strategy for the construction of spirocyclic 3(2H)-furanones and 3-pyrrolones

Binder, Joerg T.,Crone, Benedikt,Kirsch, Stefan F.,Liebert, Clemence,Menz, Helge

, p. 1636 - 1647 (2008/02/06)

Two platinum(II)-catalyzed heterocyclization-migration reactions that provide five-membered heterocycle products are described. With 5 mol-% of PtCl2 as a catalyst, 2-alkynyl-2-hydroxy carbonyl compounds 1 are converted into 3(2H)-furanones 2 a
