3,3'-bis-(dimethylamino)biphenyl, also known as 4,4'-dimethylaminobiphenyl or DMBP, is an organic compound with the chemical formula C14H18N2. It is a colorless to pale yellow crystalline solid that is soluble in organic solvents. DMBP is primarily used as a photosensitizer in the production of photoresists, which are materials used in the semiconductor industry for the transfer of patterns onto a substrate. It is also employed as a dye in various applications due to its ability to absorb light in the visible spectrum. The compound is synthesized through the reaction of biphenyl with dimethylamine, and it is characterized by its two dimethylamino groups attached to opposite ends of a biphenyl molecule. DMBP is known for its photoreactivity, which makes it suitable for applications where light-induced chemical changes are desired.

Check Digit Verification of cas no

The CAS Registry Mumber 4458-27-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,5 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4458-27:
(6*4)+(5*4)+(4*5)+(3*8)+(2*2)+(1*7)=99
99 % 10 = 9
So 4458-27-9 is a valid CAS Registry Number.
