100989-99-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 100989-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,9,8 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 100989-99:
(8*1)+(7*0)+(6*0)+(5*9)+(4*8)+(3*9)+(2*9)+(1*9)=139
139 % 10 = 9
So 100989-99-9 is a valid CAS Registry Number.

One-pot oxidation and bromination of 3,4-diaryl-2,5-dihydrothiophenes using Br2: Synthesis and application of 3,4-diaryl-2,5-dibromothiophenes

Dang, Yizhe,Chen, Yi

, p. 6901 - 6904 (2008/02/11)

(Chemical Equation Presented) A class of 3,4-diaryl-2,5-dibromothiophenes (1b-5b) was synthesized by a one-pot reaction of 3,4-diaryl-2,5- dihydrothiophenes with Br2 reagent in excellent yield (83-92%). It was found that Br2 performed a double function (oxidation and bromination) during the conversion of 3,4-diaryl-2,5-dihydrothiophenes to 3,4-diaryl-2,5-dibromothiophenes. The application of 3,4-diaryl-2,5- dibromothiophenes used as building blocks was also investigated. Employing 3,4-diphenyl-2,5-dibromothiophene (1b) as a template, a class of 2,3,4,5-tetraarylthiophenes was prepared by the Suzuki coupling reaction. This provided a new and simple approach to the preparation of 2,3,4,5- tetraarylthiophenes.

Oxidation of 3,4-diaryl-2,5-dihydrothiophenes to 3,4-diarylthiophenes using CuBr2: Simple and efficient preparation of 3,4-diarylthiophenes

Dang, Yizhe,Chen, Yi

, p. 5661 - 5664 (2008/09/17)

A class of 3,4-diarylthiophenes was prepared in excellent yield (80-91%) by oxidation of 3,4-diaryl-2,5-dihydrothiophenes with CuBr2. The approach is also available for the synthesis of 3,4-diarylpyrroles and 3,4-diarylfuran. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

GENERAL SYNTHESIS OF 2,5-DIHYDROTHIOPHENES (3-THIOLENES) FROM DIKETO SULFIDES

Nakayama, Juzo,Machida, Haruki,Hoshino, Masamatsu

, p. 1981 - 1982 (2007/10/02)

The intramolecular reductive coupling reaction of easily accesible diketo sulfides by a low-valent titanium reagent (prepared from titanium(IV) chloride and zinc powder) provides an efficient general synthesis of 2,5-dihydrothiophenes.

EFFICIENT PREPARATION OF POLYSUBSTITUTED 1,3-DIENES FROM α,α'-DIKETO SULFIDES

Nakayama, Juzo,Machida, Haruki,Saito, Ryuji,Akimoto, Keiichi,Hoshino, Masamatsu

, p. 1173 - 1176 (2007/10/02)

A series of polysubstituted 1,3-dienes were prepared in good overall yields in three steps starting from readily accessible α,α'-diketo sulfides.
