57246-12-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57246-12-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,2,4 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57246-12:
(7*5)+(6*7)+(5*2)+(4*4)+(3*6)+(2*1)+(1*2)=125
125 % 10 = 5
So 57246-12-5 is a valid CAS Registry Number.

Synthesis of new macrocyclic aryl phosphonates. X-ray structure and clathration properties

Consiglio, Giuseppe A.,Failla, Salvatore,Finocchiaro, Paolo,Hardcastle, Kenneth I.

, p. 697 - 700 (1999)

Williamson condensation of bis-o-hydroxy aryl phosphonates with dihaloalkylaryl derivatives yields the title compounds. They show interesting stereochemical aspects and some of them can be used in chiral recognitions and separations.

Synthesis of new ortho-hydroxy aryl phosphonate monomers

Consiglio, Giuseppe A.,Failla, Salvatore,Finocchiaro, Paolo,Siracusa, Valentina

, p. 413 - 418 (2007/10/03)

Commercially available bridged bis-phenols react with diethylphosphite to give bis-phosphates, which are easily transformed by LDA, in good yields, to bis-ortho hydroxy aryl phosphonates. These new monomers are of great relevance for the synthesis of nove
