Check Digit Verification of cas no

The CAS Registry Mumber 38527-56-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,5,2 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 38527-56:
(7*3)+(6*8)+(5*5)+(4*2)+(3*7)+(2*5)+(1*6)=139
139 % 10 = 9
So 38527-56-9 is a valid CAS Registry Number.

7-oxabicyclo[2.2.1]heptadiene derivatives: Reactivity towards Bronsted acids

Maggiani, Alain,Tubul, Arlette,Brun, Pierre

, p. 2495 - 2496 (1999)

7-Oxabicyclo[2.2.1]heptadiene derivatives can be converted to phenols, fulvenes and/or the products from a retro-Diels-Alder-like reaction by treatment with Bronsted acids; the outcome of the reaction depends on the experimental conditions and the nature of the Bronsted acid used.

Efficient procedure for the preparation of 2-bromofuran and its application in the synthesis of 2-arylfurans

Raheem, Mohammed-Abdul,Nagireddy, Jaipal R.,Durham, Robin,Tam, William

experimental part, p. 2138 - 2146 (2010/08/13)

A simple, straightforward, and scalable procedure for the preparation of 2-bromofuran using N-bromosuccinimide (NBS) in dimethylformamide (DMF) is reported. The described preparation is conducted on a 20 to 50g scale and does not require extractive workup procedures or chromatographic purifications. To illustrate the synthetic applications of 2-bromofuran, palladium-catalyzed Suzuki coupling reactions of the prepared 2-bromofuran with various aryl boronic acids were investigated, and moderate to good yields of 2-arylfurans were obtained.
