(8*1)+(7*9)+(6*5)+(5*2)+(4*1)+(3*2)+(2*0)+(1*4)=125
125 % 10 = 5
So 195212-04-5 is a valid CAS Registry Number.

Extremely base-resistant organic phosphazenium cations

Schwesinger, Reinhard,Link, Reinhard,Wenzl, Peter,Kossek, Sebastian,Keller, Manfred

, p. 429 - 437 (2008/09/19)

A series of peralkylated polyaminophosphazenium cations exhibiting extraordinary base resistance under phase-transfer conditions were efficiently synthesized from readily available starting materials. Their half lives under these conditions exceed those of the most stable conventional organic cations by factors of up to 3000.
