2,3-Di-(4-ethyl-phenyl)-2,3-dimethyl-butan is a complex organic compound with the molecular formula C22H26. It is characterized by a butane backbone, where both the 2nd and 3rd carbon atoms are substituted with two different phenyl groups. Each of these phenyl groups has an ethyl substituent at the para position (4th position). Additionally, the 2nd and 3rd carbon atoms of the butane chain also have methyl groups attached to them. 2,3-Di-(4-ethyl-phenyl)-2,3-dimethyl-butan is a member of the class of chemicals known as stilbenes, which are organic compounds with a double bond between two carbon atoms in a benzene ring. Stilbenes are known for their potential applications in various fields, including pharmaceuticals and materials science, due to their unique chemical properties and the ability to form derivatives with diverse functionalities.

Check Digit Verification of cas no

The CAS Registry Mumber 5171-90-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,7 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5171-90:
(6*5)+(5*1)+(4*7)+(3*1)+(2*9)+(1*0)=84
84 % 10 = 4
So 5171-90-4 is a valid CAS Registry Number.
