N-Formyl-1,2,2,2-tetrachloroethylamine is a chemical compound with the molecular formula C2Cl4NO. It is a derivative of chloroethylamine, where one of the hydrogen atoms is replaced by a formyl group (CHO), and the other three hydrogen atoms are replaced by chlorine atoms. N-Formyl-1,2,2,2-tetrachloroethylamine is characterized by its high reactivity due to the presence of the formyl group, which can participate in various chemical reactions, such as nucleophilic addition and condensation reactions. N-Formyl-1,2,2,2-tetrachloroethylamine is a colorless liquid with a pungent odor and is soluble in organic solvents. It is primarily used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals, as well as in the production of some dyes and pigments. Due to its potential toxicity and reactivity, it is important to handle N-Formyl-1,2,2,2-tetrachloroethylamine with caution and in accordance with proper safety protocols.

Check Digit Verification of cas no

The CAS Registry Mumber 3659-66-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,5 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3659-66:
(6*3)+(5*6)+(4*5)+(3*9)+(2*6)+(1*6)=113
113 % 10 = 3
So 3659-66-3 is a valid CAS Registry Number.

, p. 1619 - 1628 (2007/10/02)

The crystal structure was solved by direct methods and refined by the least squares method in a 9 x 9 block diagonal approximation using the anisotropic temperature parameters.The R-factor was decreased to a final value of 5.6percent for 970 observed reflextions.The crystal are monoclinic with a space group of P21/c and lattice parameters of a = 1.1056(11), b = 0.8913(11), c = 1.2023(16) nm, β = 96.32, and Z = 4.The crystal structure consists of discrete molecules between which hydrogen interactions of the N-HO and C-HO type were observed.The lengths of the N1-C3 (0.1432 nm) and C3-O1 (0.1203 nm) bonds and valence angles, C3-N1-C1 (119.9), N1-C3-O1 (126.5), indicate considerable delocalization of the ?-electrons and participation of the lone electrone pair on N1 nitrogen in the conjugation in the N1-C3-O1 molecular fragment.The CNDO/2 quantum chemical method was used to calculate the electron structure.Calculation for partial optimization of the dihedral angles, φ and ω, indicated that the most stable form is obtained for the values φ = 0, ψ = 120-150, 240-270 and ω = 150-210,330-30.
