Check Digit Verification of cas no
The CAS Registry Mumber 145007-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,0,0 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 145007-52:
(8*1)+(7*4)+(6*5)+(5*0)+(4*0)+(3*7)+(2*5)+(1*2)=99
99 % 10 = 9
So 145007-52-9 is a valid CAS Registry Number.

METHOD FOR THE PRODUCTION OF CYCLIC PHOSPHONIC ACID ANHYDRIDES
-
Page/Page column 8; 9, (2008/06/13)
Disclosed is a method for producing cyclic phosphonic acid anhydrides of formula (III) by a) reacting phosphonic acid derivatives of formula (I) with acetic anhydride at a temperature ranging between 30 and 150 °C while separating a mixture of ethanoic acid and acetic anhydride by means of distillation, b) then reactively distilling the oligomeric phosphonic acid anhydrides of formula (II) obtained in step a) and transforming the same into the corresponding cyclic trimeric phosphonic acid anhydrides of formula (III), n representing a number between 0 and 300 while R represents allyl, aryl, or open-chain, cyclic, or branched C1 to C8 alkyl radicals, aryloxy, allyloxy, or alkoxy comprising open-chain, cyclic, or branched C1 to C8 alkyl radicals. Preferably, the cyclic trimeric phosphonic acid anhydrides formed in step b) are immediately dissolved in an organic solvent that exhibits an inert behavior relative thereto.
