Benzene,1,1'-(1-ethylidene-1,2-ethanediyl)bis-, also known as 1,1'-(1-ethylidene-1,2-ethanediyl)bisbenzene or 1,1'-(1-ethylidene)bis(benzene), is an organic compound with the chemical formula C16H18. It is a symmetrical, rigid molecule consisting of two benzene rings connected by a central ethylidene (CH2) group, which forms a bridge between the two aromatic rings. Benzene,1,1'-(1-ethylidene-1,2-ethanediyl)bis- is a type of biphenyl derivative, where the two benzene rings are linked through a methylene bridge. It is a colorless, crystalline solid that is insoluble in water but soluble in organic solvents. The compound is used in the synthesis of various organic compounds and as a chemical intermediate in the production of pharmaceuticals and other specialty chemicals. Due to its aromatic nature, it exhibits certain chemical properties, such as electrophilic substitution reactions, which are characteristic of benzene and its derivatives.

5551-45-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5551-45-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,5 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5551-45:
(6*5)+(5*5)+(4*5)+(3*1)+(2*4)+(1*5)=91
91 % 10 = 1
So 5551-45-1 is a valid CAS Registry Number.
