Check Digit Verification of cas no

The CAS Registry Mumber 935510-48-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,5,5,1 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 935510-48:
(8*9)+(7*3)+(6*5)+(5*5)+(4*1)+(3*0)+(2*4)+(1*8)=168
168 % 10 = 8
So 935510-48-8 is a valid CAS Registry Number.

(Chemical Equation Presented) This paper describes the self-assembly of a new class of three-component dynamic [2]catenanes, which are driven or stabilized by intramolecular hydrogen bonding, coordination, and electrostatic interaction. One of the component molecules 2, consisting of an aromatic oligoamide spacer and two peripheral zinc porphyrin units, was designed to adopt a folded preorganized conformation, which is stabilized by consecutive intramolecular three-centered hydrogen bonds. Component molecule 3 is a linear secondary ammonium bearing two peripheral pyridine units, which was designed to form a 1:1 complex with 24-crown-8 (5). The 1H NMR and UV-vis experiments in CDCl3-CD3CN (4:1 v/v) revealed that, due to the preorganized U-shaped feature, 2 could efficiently bind 3 through the cooperative zinc-pyridine coordination to generate highly stable 1:1 complex 2·3. Adding 5 to the 1:1 solution of 2 and 3 led to the formation of dynamic three-component [2]catenane 2·3·5 as a result of the threading of 3 through 5. 1H NMR studies indicated that in the 1:1:1 solution (3 mM) [2]catenane 2·3·5 was generated in 55% yield at 25°C. The yield was increased with the reduction of the temperature and [2]catenane could be produced quantitatively in a 1:1:2 solution ([2] = 3 mM) at -13°C. Replacing 3 with 1,2-bis(4,4′-bipyridinium)ethane (4) in the three-component solution could also give rise to similar dynamic [2]-catenane 2·4·5 albeit in slightly lower yield.
