Check Digit Verification of cas no
The CAS Registry Mumber 26964-04-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,9,6 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 26964-04:
(7*2)+(6*6)+(5*9)+(4*6)+(3*4)+(2*0)+(1*4)=135
135 % 10 = 5
So 26964-04-5 is a valid CAS Registry Number.

Reaction of Epoxides with Metaphosphoric Acid Derivatives
Bodalski, Ryszard,Quin, Louis D.
, p. 2666 - 2671 (2007/10/02)
Ethyl metaphosphate (EtOPO2), eliminated in the thermolysis of the bridged cyclic phosphonate endo-3-ethoxy-6-methyl-N-phenyl-2,3-oxabicyclooct-5-ene-8,9-dicarboximide 3-oxide, has been found to cause ring opening of epoxides, resulting in formation of 2-ethoxy-4-substituted 1,3,2-dioxaphospholane 2-oxides as major products.N,N-Diethyl metaphosphoramidate (Et2NPO2) reacted similarly.With ethyl metathiophosphate (EtOP(S)O), the 1,3,2-oxathiaphospholane 2-oxide ring was formed.Products of these reactions were characterized by 31P NMR spectroscopy and by GC-MS.These reactions are presumed to be initiated by electrophilic attack of the metaphosphate on the epoxide oxygen to form a cyclic oxonium ion.
