127143-28-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 127143-28-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,1,4 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127143-28:
(8*1)+(7*2)+(6*7)+(5*1)+(4*4)+(3*3)+(2*2)+(1*8)=106
106 % 10 = 6
So 127143-28-6 is a valid CAS Registry Number.

Chlorination of Conjugated Nitroalkenes with PhICl 2and so 2Cl 2for the Synthesis of α-Chloronitroalkenes

Fadeeva, Anastasia A.,Ioffe, Sema L.,Tabolin, Andrey A.

supporting information, p. 2679 - 2688 (2020/11/02)

Chlorination of conjugated nitroalkenes with iodobenzene dichloride or sulfuryl chloride to give target α-chloronitroalkenes in good yields is described. Details of the procedure depend on the donating ability of the nitroalkene substituents. The activity of the described chlorinating agents increases in order 'PhICl 2/Py' 2Cl 2' 2Cl 2/HCl' with the former producing the best yields for highly donating substrates and the latter for non-activated groups. An autocatalytic role of hydrogen chloride and the chemoselectivity of chlorination were also demonstrated.
