Check Digit Verification of cas no

The CAS Registry Mumber 1621-90-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,2 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1621-90:
(6*1)+(5*6)+(4*2)+(3*1)+(2*9)+(1*0)=65
65 % 10 = 5
So 1621-90-5 is a valid CAS Registry Number.

4-Nitrosopyridine 1-Oxide compared with Other 4-Substituted Pyridine 1-Oxides as evidenced by Carbon-13 NMR Spectra and Dipole Moments

Gowenlock, Brian G.,Cameron, Mailer,Boyd, Alan S. F.

, p. 358 - 359 (2007/10/03)

Previously unreported physical properties of 4-Nitrosopyridine 1-oxide have been measured; the 13C NMR spectrum is compared with that for other 4-substituted pyridine 1-oxides and it is suggested that the electronic properties of the nitroso group and of other ?-electron-accepting groups are dominated by the N+-O- dipole, this being mirrored by dipole-moment measurements.
