Check Digit Verification of cas no
The CAS Registry Mumber 6940-58-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,4 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6940-58:
(6*6)+(5*9)+(4*4)+(3*0)+(2*5)+(1*8)=115
115 % 10 = 5
So 6940-58-5 is a valid CAS Registry Number.

Synthesis and conformation studies of a dodecaazanonacyclotetratetracontane

Compound 3 was prepared by self-assembly of 1,3,5-pentanetriamine and aqueous formaldehyde in quantitative yield (Figure 1). This molecule can exist in four well-defined diamond-lattice conformations of symmetries D(2d), S4, C(2v) and D(2d). Low-temperature 13C NMR spectroscopy indicates the existence of three main conformers; their relative populations depend on the solvent used. An extra set of low- intensity lines is also observed. A conformation interconversion scheme is proposed; it involves two additional less populated quasi-diamond-lattice intermediates derived from a helix compressed along its axis. One of these is trapped as a 1:2 clathrate with 1,4-dioxane; its crystal structure is reported.
