1,2,5-Oxadiazole is a five-membered, heteroaromatic, planar heterocycle comprised of one oxygen atom with two vicinal nitrogen atoms (N-O-N) and two carbon atoms at the 3and 4-positions of the ring. It is a π-excessive heterocycle also referred to by its trivial name furazan and corresponding 2-N-oxide as furoxan. The ionization energy of oxadiazole is 11.79 eV and the dipole moment is 3.38 D greater than isoxazole. The π electron density of the nitrogen atom is greater than the oxygen and carbon atoms.

Check Digit Verification of cas no

The CAS Registry Mumber 288-37-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,8 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 288-37:
(5*2)+(4*8)+(3*8)+(2*3)+(1*7)=79
79 % 10 = 9
So 288-37-9 is a valid CAS Registry Number.
