Check Digit Verification of cas no

The CAS Registry Mumber 156876-16-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,8,7 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 156876-16:
(8*1)+(7*5)+(6*6)+(5*8)+(4*7)+(3*6)+(2*1)+(1*6)=173
173 % 10 = 3
So 156876-16-3 is a valid CAS Registry Number.

SYNTHETIC, SPECTROSCOPIC AND CRYSTALLOGRAPHIC STUDIES OF HETEROFUNCTIONAL DIPHOSPHAZANE LIGANDS

Babu, R. P. Kamalesh,Aparna, K.,Krishnamurthy, S. S.,Nethaji, M.

, p. 39 - 54 (2007/10/02)

New unsymmetrical diphosphazanes of the type X2PN(Pri)PYY' are prepared and converted into their mono- and di-oxides or sulfides.These can function as heterofunctional ligands through P,S,N or O donor sites.These compounds have been characterized by NMR spectroscopic studies.Variable temeprature 31P NMR measurements on some of these compounds reveal the presence of different types of conformers in solution.Single crystal X-ray diffraction studies have been carried out for Ph2(S)N(Pri)PPh(N2C3HMe2-3,5) (2g) and Ph2P(O)N(Pri)P(O)Ph(OC5H4N-2) (5h). Key words: Unsymmetrical diphosphazanes; their monosulfides, monoxides and dioxides; syntheses; NMR spectra; crystal structures.
