78428-88-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78428-88-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,4,2 and 8 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 78428-88:
(7*7)+(6*8)+(5*4)+(4*2)+(3*8)+(2*8)+(1*8)=173
173 % 10 = 3
So 78428-88-3 is a valid CAS Registry Number.

New Synthetic Route for the Preparation of 4-Phenylthio-4-butanolide Derivatives by the Use of the Pummerer Rearrangement

Watanabe, Mikio,Nakamori, Seijin,Hasegawa, Hatsue,Shirai, Kozo,Kumamoto, Takanobu

, p. 817 - 821 (2007/10/02)

The Pummerer rearrangement reaction of 2- or 3-substituted 4-(phenylsulfinyl)butyric acids in the presence of an excess amount of acetic anhydride and a catalytic amount of p-toluenesulfonic acid in refluxing toluene for 1 h afforded 2- or 3-substituted 4-phenylthio-4-butanolide (17a-f).Thermolysis in pyridine of 4-phenylsulfinyl 4-butanolides, which were prepared by oxidation of 17a-f, afforded 2- or 3-substituted 2- or 3-buten-4-olides.
