Check Digit Verification of cas no

The CAS Registry Mumber 15051-28-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,0,5 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 15051-28:
(7*1)+(6*5)+(5*0)+(4*5)+(3*1)+(2*2)+(1*8)=72
72 % 10 = 2
So 15051-28-2 is a valid CAS Registry Number.

Synthesis and structure of cyclic oligo(p-phenylene oxide)s, -(C 6H4O)n- (n = 6-10)

Takeuchi, Daisuke,Asano, Itaru,Osakada, Kohtaro

, p. 8614 - 8617 (2007/10/03)

Stepwise growth of oligo(p-phenylene oxide)s and cyclization via the Ullmann coupling reaction by using CuI/N,N-dimethylglycine afforded cyclic oligo(p-phenyleneoxide)s, -(C6H4O)n-(n = 6-10). The structure of the new cyclophanes was determined by X-ray crystallography, which revealed that they have planar or slightly bent structures with diameters of 1.0-1.5 nm.
