4,4'-Bis-<4-dimethylamino-benzylidenamino>-diphenyldisulfid, also known as Michler's Ketone, is an organic compound with the chemical formula C26H26N2S2. It is a yellow crystalline solid that is soluble in organic solvents and slightly soluble in water. 4,4'-Bis-<4-dimethylamino-benzylidenamino>-diphenyldisulfid is primarily used as a dyestuff, particularly in the production of fluorescent brightening agents and as a photosensitizer in the polymer industry. It is also employed as a reagent in chemical analysis and as a pigment in the printing industry. Michler's Ketone is known for its photosensitivity, which makes it useful in applications where light-induced reactions are desired. However, due to its potential health and environmental concerns, its use is regulated, and it is classified as a hazardous substance.

Check Digit Verification of cas no

The CAS Registry Mumber 3430-52-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,3 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3430-52:
(6*3)+(5*4)+(4*3)+(3*0)+(2*5)+(1*2)=62
62 % 10 = 2
So 3430-52-2 is a valid CAS Registry Number.
