Check Digit Verification of cas no

The CAS Registry Mumber 71265-09-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,2,6 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 71265-09:
(7*7)+(6*1)+(5*2)+(4*6)+(3*5)+(2*0)+(1*9)=113
113 % 10 = 3
So 71265-09-3 is a valid CAS Registry Number.

Halodephosphorylation of α,β-unsaturated phosphonic acid monoesters

Lahrache, Hind,Robin, Sylvie,Rousseau, Gérard

, p. 1635 - 1637 (2005)

Reaction of α,β-ethylenic and acetylenic phosphonic acid monoesters with (biscollidine)iodine(I) or (biscollidine)bromine(I) hexafluorophosphate led to α,β-unsaturated halides by, without precedent, dephosphorylation reactions.

Acylphosphonates as Substrates for Wittig and Horner-Wittig Reactions. Unusual Stereoselectivity in the Synthesis of β-Phosphinoylacrylates

Harris, Roger L. N.,McFadden, Helen G.

, p. 417 - 424 (2007/10/02)

Phosphorus-stabilized carbanions with additional stabilizing groups react with dialkyl acylphosphonates (alkanoyl- and aroyl-phosphonates) to give fair to good yields of dialkyl vinylphoshponates, with some limitations imposed by competing side reactions
