87275-35-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87275-35-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,7 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 87275-35:
(7*8)+(6*7)+(5*2)+(4*7)+(3*5)+(2*3)+(1*5)=162
162 % 10 = 2
So 87275-35-2 is a valid CAS Registry Number.

Studies on the Synthesis of Heterocyclic Compounds. XI. Cleavage of 1,3-Benzodioxoles by Magnesium Bromide-Acetic Anhydride

Bonsignore, Leonardo,Fadda, Anna Maria,Loy, Giuseppe,Maccioni, Antonio,Podda, Gianni

, p. 703 - 707 (2007/10/02)

The cleavage reaction of some 1,3-benzodioxole derivatives with magnesium bromide and acetic anhydride has been studied.The reactions have been carried out in acetonitrile solution at room temperature.In all of the 1,3-benzodioxoles studied, the opening of the heterocyclic ring with formation of bromides, alkenes and their corresponding products of hydrolysis have been observed.The competitive electrophilic substitution on the benzene ring was very limited and was insignificant when a large excess of the cleavage reagent was used.The structures of newly prepared compounds have been determined by elemental analysis, spectroscopic data and comparison with authentic samples.
