88089-38-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 88089-38-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,0,8 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 88089-38:
(7*8)+(6*8)+(5*0)+(4*8)+(3*9)+(2*3)+(1*8)=177
177 % 10 = 7
So 88089-38-7 is a valid CAS Registry Number.

Electrophilicities of 1,2-disubstituted ethylenes

Allgaeuer, Dominik S.,Mayr, Herbert

, p. 2956 - 2963 (2014/05/20)

The kinetics of the reactions of maleic anhydride, N-methylmaleimide, fumaronitrile, diethyl fumarate, and diethyl maleate with pyridinium and sulfonium ylides were studied in DMSO at 20 C. All of the reactions were found to follow a second-order rate law

Cycloaddition of Pyridinium Methylides with Electron-Deficient Olefins and Silica-Gel Mediated Elimination of Pyridines from the Cycloadducts: A New Method of Alkylation or Hydroalkylidenation of Olefins

Tsuge, Otohiko,Kanemasa, Shuji,Takenaka, Shigeori

, p. 1489 - 1496 (2007/10/02)

Pyridinium methylides bearing an anion-stabilizing substituent at the ylide carbon react with a variety of olefins carrying two electron-withdrawing groups at the both carbons such as N-substituted maleimides, a citraconimide, dimethyl maleate, dimethyl f

STEREOSELECTIVE HYDROALKYLIDENATION OF OLEFIN WITH PYRIDINIUM METHYLIDES

Tsuge, Otohiko,Kanemasa, Shuji,Takenaka, Shigeori,Kuraoka, Satoru

, p. 465 - 468 (2007/10/02)

Acid-catalyzed elimination of pyridine from the stereoselective cycloadducts between electron-deficient olefins and pyridinium methylides with ylide-stabilizing substituents offers a new type of C-C bond formation.
