Check Digit Verification of cas no

The CAS Registry Mumber 120232-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,2,3 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 120232-75:
(8*1)+(7*2)+(6*0)+(5*2)+(4*3)+(3*2)+(2*7)+(1*5)=69
69 % 10 = 9
So 120232-75-9 is a valid CAS Registry Number.

Synthesis of phosphonic acid alkylesteramides as structural analogues of sulfadimidine and acetophenetidin

Buseck,Neidlein

, p. 193 - 197 (1993)

The phosphonic acid alkylesteramides 19 and 36 were synthesized as structural analogues of sulfadimidine and acetophenetidin. 19 was not obtained by nucleophilic aromatic substitution, but by catalytic reduction of the corresponding nitro derivative. Condensation of the phosphonic acid diethylester 13 with aromatic aldehydes and following reduction yielded the amines 26-28.

Alkylesters and N,N-Dimethylaminoethylesters of Unsymmetrical Phosphinic Acids

Neidlein, R.,Buseck, S.

, p. 309 - 318 (2007/10/02)

The phosphinic acid chlorides 6 and 9 react in good yields with N,N-dimethylaminoethanol to the corresponding esters 3 and 10.Reaction of the phenylphosphonous acid esters 1 and 2 with arylbromides, heteroarylbromides and carboxylic acid chlorides give es
