General Description
Diethyl tert-butylphosphonate is a chemical compound that is generally used in chemistry as a reagent or as a component in the synthesis of other complex molecules. Its molecular formula is C9H21O3P and it falls under the class of organophosphorus compounds. This chemical belongs to phosphonates, which are basically phosphoric acid derivatives. Diethyl tert-butylphosphonate is non-volatile, it has comparatively low toxicity but it may cause irritation to skin and eyes. With appropriate storing and handling, it is a useful compound in a variety of manufacturing processes, particularly in the pharmaceutical industry.
Check Digit Verification of cas no
The CAS Registry Mumber 19935-93-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,3 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 19935-93:
(7*1)+(6*9)+(5*9)+(4*3)+(3*5)+(2*9)+(1*3)=154
154 % 10 = 4
So 19935-93-4 is a valid CAS Registry Number.

The design and synthesis of a novel organophosphorus compound containing the structure of both β-amino acid and β-aminophosphonate
Teng, Han Bing
scheme or table, p. 810 - 812 (2011/11/13)
A novel organophosphorus compound containing the structure of both b-amino acid and b-aminophosphonate is designed and synthesized. Arbuzov reaction with P(OEt)3, the N-Boc protected iodide 3 cannot provide the desired product but 2-oxazolidinone 4 because of the neighboring-group participation of the Boc moiety. To avoid the intramolecular participation of the carbamates, the Ts protecting group is employed and the Ts-protected iodide 5 affords the target product successfully.
