Check Digit Verification of cas no

The CAS Registry Mumber 1427288-31-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,7,2,8 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1427288-31:
(9*1)+(8*4)+(7*2)+(6*7)+(5*2)+(4*8)+(3*8)+(2*3)+(1*1)=170
170 % 10 = 0
So 1427288-31-0 is a valid CAS Registry Number.

'Click' functionalised polymer resins: A new approach to the synthesis of surface attached bipyridinium and naphthalene diimide [2]rotaxanes

Wilson, Hannah,Byrne, Sean,Bampos, Nick,Mullen, Kathleen M.

, p. 2105 - 2115 (2013)

Herein we describe the design and synthesis of a series of solid-tethered [2]rotaxanes utilising crown ether-naphthalene diimide or crown ether-bipyridinium host guest interactions. TentaGel polystyrene resins were initially modified in a two-stage procedure to azide functionalised beads before the target supramolecular architectures were attached using a copper catalysed click procedure. The final assembly was examined using IR spectroscopy and gel-phase 1H High Resolution Magic Angle Spinning (HR MAS) NMR spectroscopy. The HR MAS technique enabled a direct comparison between the solid-tethered architectures and the synthesis and characterisation of analogous solution-based [2]rotaxanes to be made.
