40397-95-3 Usage
General Description
2-CHLORO-4-NITROPHENYL ISOCYANATE is a chemical compound with the molecular formula C7H3ClN2O3. It is a yellow crystalline solid that is primarily used in the production of pharmaceuticals, agrochemicals, and dyes. It is an isocyanate, a functional group that is commonly used in the synthesis of polyurethane polymers. 2-CHLORO-4-NITROPHENYL ISOCYANATE is a highly reactive compound and should be handled with care due to its potential to cause irritation to the skin, eyes, and respiratory system. It is also a potential allergen and sensitizer, making proper safety precautions essential when working with this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 40397-95-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,9 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 40397-95:
(7*4)+(6*0)+(5*3)+(4*9)+(3*7)+(2*9)+(1*5)=123
123 % 10 = 3
So 40397-95-3 is a valid CAS Registry Number.
