Used in Polyurethane Foam Production:
Tris(chloromethyl)phosphine oxide also serves as a stabilizer in the production of polyurethane foam. Its inclusion contributes to the stability and performance of the foam, which is used in various industries, including construction, furniture, and bedding.
It is crucial to handle Tris(chloromethyl)phosphine oxide with care due to its toxicity and potential to cause irritation to the skin, eyes, and respiratory tract. Moreover, as an environmental contaminant, proper handling and disposal are essential to mitigate ecological risks.
Check Digit Verification of cas no
The CAS Registry Mumber 4851-89-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,5 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.Calculate Digit Verification of CAS Registry Number 4851-89:
(6*4)+(5*8)+(4*5)+(3*1)+(2*8)+(1*9)=112
112 % 10 = 2
So 4851-89-2 is a valid CAS Registry Number.
