Check Digit Verification of cas no

The CAS Registry Mumber 85450-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,4,5 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 85450-57:
(7*8)+(6*5)+(5*4)+(4*5)+(3*0)+(2*5)+(1*7)=143
143 % 10 = 3
So 85450-57-3 is a valid CAS Registry Number.

Preparation and Properties of Difluorophosphino-derivatives of Phosphorus(V) Hydroxy-compounds

Ebsworth, E. A. V.,Hunter, George M.,Rankin, David W. H.

, p. 245 - 248 (1983)

Phosphoric acid and other hydroxy-derivatives of phosphorus(V) react with S(PF2)2 to give difluorophosphino-esters.Tris(difluorophosphino) phosphate, PO(OPF2)3, and bis(difluorophosphino) monofluorophosphate, PFO(OPF2)2, have been prepared and characterised by n.m.r., mass, and vibrational spectroscopy.The reaction of PO(OPF2)3 with diborane is described.The formation and n.m.r. spectra of PO(OPF2)2Ph and PO(OPF2)Ph2 are also reported.
