166537-88-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 166537-88-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,5,3 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 166537-88:
(8*1)+(7*6)+(6*6)+(5*5)+(4*3)+(3*7)+(2*8)+(1*8)=168
168 % 10 = 8
So 166537-88-8 is a valid CAS Registry Number.

Synthesis of Functionalized Pyrrolines via Microwave-Promoted Iminyl Radical Cyclizations

Singh, Jatinder,Nickel, Garrison A.,Cai, Yu,Jones, Dakota D.,Nelson, Tanner J.,Small, Jeshurun E.,Castle, Steven L.

supporting information, p. 3970 - 3974 (2021/05/26)

O-Phenyloximes tethered to alkenes undergo 5-exo-trig iminyl radical cyclizations upon microwave irradiation. Trapping of the resulting cyclic radicals results in C-C, C-N, C-O, C-S, or C-X bond formation. Allylic sulfides undergo a tandem cyclization-thi

New synthesis of 3-fluoropyrroles

Surmont, Riccardo,Verniest, Guido,Colpaert, Filip,Macdonald, Gregor,Thuring, Jan Willem,Deroose, Frederik,De Kimpe, Norbert

body text, p. 1377 - 1380 (2009/06/28)

5-Alkoxymethyl-2-aryl-3-fluoro-1H-pyrroles and 2-aryl-3-fluoro-1H-pyrrole- 5-carbaldehydes were efficiently prepared from the corresponding 2-aryl-5-(bromomethyl)-1-pyrrolines via electrophilic α, α-difluorination of the imino bond, using Selectfluor (1-c

Synthesis of dihydropyrrole derivatives by copper-catalyzed cyclization of γ, δ-unsaturated ketone O-methoxycarbonyloximes

Koganemaru, Yohei,Kitamura, Mitsuru,Narasaka, Koichi

, p. 784 - 785 (2007/10/03)

2-Bromomethyl-3,4-dihydro-2H-pyrroles are prepared from γ, δ-unsaturated ketone O-methoxycarbonyloximes by treatment with a catalytic amount of CuBr·SMe2 and LiBr.
