Check Digit Verification of cas no

The CAS Registry Mumber 524725-07-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,4,7,2 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 524725-07:
(8*5)+(7*2)+(6*4)+(5*7)+(4*2)+(3*5)+(2*0)+(1*7)=143
143 % 10 = 3
So 524725-07-3 is a valid CAS Registry Number.

Synthesis of bis- and tris-organophosphorus substituted amines and amino acids with PCH2N Fragments

Prishchenko, Andrey A.,Livantsov, Mikhail V.,Novikova, Olga P.,Livantsova, Ludmila I.,Petrosyan, Valery S.

, p. 430 - 440 (2010)

The aminomethylation of the derivatives of trivalent organophosphorus acids, containing PH and POSiMe3 fragments with various bis- and tris(alkoxymethyl)amines and bis(alkoxymethyl)amino acids, is proposed as a convenient method for the synthesis of new bis- and trisphosphorylated amines and amino acids as well as their derivatives with four and five coordinated phosphorus. Also the three-components systems of phosphorous acid, paraformaldehyde, and amines are thoroughly investigated via the treatment of reaction mixtures with bis(trimethylsilyl)amine.
