Check Digit Verification of cas no

The CAS Registry Mumber 1608108-44-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,8,1,0 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1608108-44:
(9*1)+(8*6)+(7*0)+(6*8)+(5*1)+(4*0)+(3*8)+(2*4)+(1*4)=146
146 % 10 = 6
So 1608108-44-6 is a valid CAS Registry Number.

An approach for rapid increase in molecular complexity: Atom economic routes to fused polycyclic ring systems

Trost, Barry M.,Ehmke, Veronika

, p. 2708 - 2711 (2014)

A protocol for the asymmetric trimethylenemethane (TMM) [3 + 2] cycloaddition reaction of alkynyl-substituted TMM donors and unsaturated N-acyl pyrroles employing a chiral bisdiamidophosphite ligand has been developed. This process generates alkynyl-substituted cyclopentanes in high yields and diastereo- and enantioselectivities. These chiral precursors are employed for the atom economic assembly of fused polycyclic hydrocarbons with hydroindene, hydroazulene, and hydrocyclopentanaphthalene scaffolds by consecutive cycloaddition reactions.
