Check Digit Verification of cas no

The CAS Registry Mumber 1290572-56-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,0,5,7 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1290572-56:
(9*1)+(8*2)+(7*9)+(6*0)+(5*5)+(4*7)+(3*2)+(2*5)+(1*6)=163
163 % 10 = 3
So 1290572-56-3 is a valid CAS Registry Number.

Thermally reversible dendronized linear ab step-polymers via "click" chemistry

Polaske, Nathan W.,McGrath, Dominic V.,McElhanon, James R.

experimental part, p. 3203 - 3210 (2012/03/07)

The synthesis and characterization of thermally labile dendronized linear AB step-polymers is described. First through third generation dendritic AB monomers 14a-c containing both a furan and furan-protected maleimide functionality were prepared by the Cu(I)-catalyzed azide-alkyne cycloaddition reaction followed by polymerization via the thermally reversible furan-maleimide Diels-Alder reaction. The assembly, disassembly, and reassembly behavior of linear dendronized step-polymers 16a-c was studied by GPC.
