3,6,10,13-Tetraoxapentacyclo[7.5.0.02,8.04,12.05,11]tetradecane, also known as cucurbit[7]uril, is a macrocyclic compound with a unique molecular structure consisting of seven carbon atoms and four oxygen atoms, forming a cyclic shape. This chemical is a member of the cucurbit[n]uril family, which are known for their ability to form inclusion complexes with various guest molecules due to their hydrophobic cavity and hydrophilic portals. Cucurbit[7]uril has potential applications in supramolecular chemistry, drug delivery, and molecular recognition, as it can selectively bind and transport specific molecules. Its structure and properties make it an interesting subject for research in material science and chemistry.

257-32-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 257-32-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,5 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 257-32:
(5*2)+(4*5)+(3*7)+(2*3)+(1*2)=59
59 % 10 = 9
So 257-32-9 is a valid CAS Registry Number.
