(E)-1-bromo-4-((4-methylstyryl)sulfonyl)benzene is an organic chemical compound characterized by a unique molecular structure. It features a benzene ring with a bromine atom at the 1st position and a sulfonyl group attached to the 4th position. The sulfonyl group is linked to a 4-methylstyryl moiety, which itself is a derivative of styrene with a methyl group. (E)-1-bromo-4-((4-methylstyryl)sulfonyl)benzene is significant in organic synthesis and may have applications in the pharmaceutical and chemical industries due to its potential reactivity and the ability to form various derivatives. Its (E) configuration indicates the geometric arrangement of the double bond in the 4-methylstyryl group, which is crucial for understanding its chemical properties and potential reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 27691-25-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,6,9 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 27691-25:
(7*2)+(6*7)+(5*6)+(4*9)+(3*1)+(2*2)+(1*5)=134
134 % 10 = 4
So 27691-25-4 is a valid CAS Registry Number.

Revealing the metal-like behavior of iodine: An iodide-catalysed radical oxidative alkenylation

Tang, Shan,Wu, Yong,Liao, Wenqing,Bai, Ruopeng,Liu, Chao,Lei, Aiwen

supporting information, p. 4496 - 4499 (2014/04/17)

In this work, we have described an alternative alkenylation approach to illustrate the metal-like behaviour of iodine in cross-coupling reactions. Alkenylation could proceed through iodide catalysed radical initiation, radical addition and iodine promoted
