Check Digit Verification of cas no

The CAS Registry Mumber 189031-70-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,0,3 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 189031-70:
(8*1)+(7*8)+(6*9)+(5*0)+(4*3)+(3*1)+(2*7)+(1*0)=147
147 % 10 = 7
So 189031-70-7 is a valid CAS Registry Number.

On the faciality of intramolecular Palladium(0)-Catalysed 'metallo-ene-type' cyclisations

Oppolzer, Wolfgang,Stammen, Blanda

, p. 3577 - 3586 (1997)

The palladium-calalysed 'metallo-ene' step in a cyclisation/β-elimination reaction sequence has been shown to be suprafacial with respect to the olefinic component. This reaction has been applied to the synthesis of a trisubstituted exocyclic alkenyl pyrrolidine with complete stereocontrol.
