Check Digit Verification of cas no

The CAS Registry Mumber 190258-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,2,5 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 190258-40:
(8*1)+(7*9)+(6*0)+(5*2)+(4*5)+(3*8)+(2*4)+(1*0)=133
133 % 10 = 3
So 190258-40-3 is a valid CAS Registry Number.

Formation of Angularly-Fused Triquinanes by Successive Use of the Pauson-Khand Reaction and Radical Closure

Clive, Derrick L. J.,Cole, Derek C.,Tao, Yong

, p. 1396 - 1406 (2007/10/02)

Angularly-fused triquinanes (see Table 1) are accessible by sequential use of the Pauson-Khand reaction and radical cyclization.The Pauson-Khand step works in the presence of homolyzable bonds, such as C-Br and C-SePh.The method seems best suited to the p
