5,5'-ureylenedi-o-tolyl diisocyanate, also known as 2,2'-ureylenebis(4-methylphenol) diisocyanate, is a chemical compound with the molecular formula C17H16N2O2. It is a white crystalline solid that is widely used in the production of polyurethane foams, elastomers, and coatings due to its high reactivity and versatility. This diisocyanate is synthesized by reacting 2,4-tolylene diisocyanate with 2,4-dimethylphenol, resulting in a compound that exhibits excellent adhesion, flexibility, and durability in various applications. However, it is also known for its potential health risks, as exposure to diisocyanates can cause respiratory and skin irritation, making it essential to handle this chemical with proper safety measures.

5206-52-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5206-52-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,0 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5206-52:
(6*5)+(5*2)+(4*0)+(3*6)+(2*5)+(1*2)=70
70 % 10 = 0
So 5206-52-0 is a valid CAS Registry Number.
