Check Digit Verification of cas no
The CAS Registry Mumber 36847-10-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,8,4 and 7 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 36847-10:
(7*3)+(6*6)+(5*8)+(4*4)+(3*7)+(2*1)+(1*0)=136
136 % 10 = 6
So 36847-10-6 is a valid CAS Registry Number.

We synthesized pyrimidine-4,6-diyl bis(tert-butyl nitroxide) (pmbNO), and characterized as a biradical by means of ESR spectroscopy. The zero-field splitting parameters were |D|/hc = 2.52 × 10-2 cm-1 and |E|/hc = 2.34 × 10-3 cm-1 in frozen toluene at 100 K. Magnetic study clarified the presence of intramolecular ferromagnetic coupling with 2J/kB = +18.5(5) K in frozen toluene-ethanol. DFT calculation supports the ground triplet state of pmbNO. The reaction of pmbNO with Cu(hfac)2 gave [Cu3(pmbNO)2(hfac) 4], and the structure was determined by X-ray crystallographic analysis. Though the ligand was reduced to be an anion radical, pmbNO is confirmed to work as a rigid bridge, and the nitroxide oxygen atoms can ligate the metal ions.
