Check Digit Verification of cas no

The CAS Registry Mumber 134149-24-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,1,4 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 134149-24:
(8*1)+(7*3)+(6*4)+(5*1)+(4*4)+(3*9)+(2*2)+(1*4)=109
109 % 10 = 9
So 134149-24-9 is a valid CAS Registry Number.

Cyclisation of ω-unsaturated β-dicarbonylcompounds catalyzed by a palladium hydride species

Monteiro,Balme,Gore

, p. 1645 - 1648 (1991)

When treated with potassium t-butoxide and then with a palladium(0) complex, the title compounds 1, 2, or 9 are smoothly cyclized by an attack of the enolates onto the unsaturation assisted by a palladium(II) species of tBuO-Pd-H type. The formation of a
