Bis-cyclohexylidenemethyl-ether, also known as 1,1'-oxybis[cyclohexane] or DCH, is an organic compound with the chemical formula C14H26O. It is a colorless, viscous liquid that is insoluble in water but soluble in organic solvents. DCH is primarily used as a plasticizer and a solvent, particularly in the production of polyvinyl chloride (PVC) and cellulose derivatives. It is also employed as a stabilizer in the manufacturing of various polymers and resins. Due to its low volatility and high boiling point, DCH is considered a safer alternative to other plasticizers, such as phthalates. However, it is essential to handle it with care, as it can cause irritation to the eyes, skin, and respiratory system.
The CAS Registry Mumber 4973-38-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,7 and 3 respectively; the second part has 2 digits, 3 and 8 respectively. Calculate Digit Verification of CAS Registry Number 4973-38: (6*4)+(5*9)+(4*7)+(3*3)+(2*3)+(1*8)=120 120 % 10 = 0 So 4973-38-0 is a valid CAS Registry Number.
