934-31-6 Usage
General Description
4,5-DICYANO-1,3-DITHIOL-2-ONE, also known as DCTO, is a chemical compound with the molecular formula C3HN3OS2. It is a yellow, crystalline powder that is sparingly soluble in water. DCTO is commonly used as a corrosion inhibitor in metalworking fluids and as a vulcanization accelerator in the rubber industry. It is also used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and dyes. DCTO is known to be a strong irritant to the skin, eyes, and respiratory system, and should be handled with care. Additionally, its exact effects on human health and the environment are not well studied, so precautions should be taken when handling and disposing of this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 934-31-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 934-31:
(5*9)+(4*3)+(3*4)+(2*3)+(1*1)=76
76 % 10 = 6
So 934-31-6 is a valid CAS Registry Number.
