Benzene, 1,1'-[2-butyne-1,4-diylbis(oxy)]bis[4-methyl- is a complex organic compound with the chemical formula C18H22O4. It is a derivative of benzene, featuring a central benzene ring with two 4-methylphenyl groups attached via a 2-butyne-1,4-diylbis(oxy) bridge. This structure consists of a butyne chain (a carbon-carbon triple bond separated by two single bonds) connected to two oxygen atoms, which in turn link the two methylphenyl groups. The compound is characterized by its symmetrical structure and the presence of methyl groups on the phenyl rings, which may influence its chemical properties and reactivity. It is important to note that Benzene, 1,1'-[2-butyne-1,4-diylbis(oxy)]bis[4-methyl-, like many organic chemicals, should be handled with care due to potential health and environmental impacts.

4200-18-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4200-18-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,0 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4200-18:
(6*4)+(5*2)+(4*0)+(3*0)+(2*1)+(1*8)=44
44 % 10 = 4
So 4200-18-4 is a valid CAS Registry Number.
