100990-31-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 100990-31-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,9,9 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 100990-31:
(8*1)+(7*0)+(6*0)+(5*9)+(4*9)+(3*0)+(2*3)+(1*1)=96
96 % 10 = 6
So 100990-31-6 is a valid CAS Registry Number.

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.

PREPARATION OF 1-PHENYLTHIO-1,3-DIENES BY REACTION OF 2,5-DIHYDROTHIOPHENES WITH BENZYNE THROUGH FRAGMENTATION OF SULFONIUM YLIDE INTERMEDIATES

Nakayama, Juzo,Kumano, Yuichi,Hoshino, Masamatsu

, p. 847 - 850 (2007/10/02)

The reaction of a series of 2,5-dihydrothiophenes with benzyne, generated from 2-carboxybenzenediazonium chloride, affords 1-phenylthio-1,3-dienes in good yields through the fragmentation of sulfonium ylide intermediates.

GENERAL SYNTHESIS OF POLYSUBSTITUTED THIOPHENES FROM DIKETO SULFIDES

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

, p. 1983 - 1984 (2007/10/02)

Treatment of diketo sulfides with a low-valent titanium reagent at 0 deg C (in two cases at room temperature) affords 3,4-dihydroxythiolanes in good yields.The acid-catalyzed (p-toluenesulfonic acid) dehydration of the latter compounds leads to the corres
