General Description
1,2-Pyrrolidinedicarboximide,2-methyl-5-oxo-(7CI,8CI), also known as N-Methyl-2-pyrrolidone (NMP), is a chemical compound commonly used as a solvent in various industrial applications such as pharmaceuticals, electronics, and agrochemicals. It is a colorless liquid with a slightly amine-like odor and is known for its high solvency and chemical stability. NMP is an important intermediate in the production of resins, polymers, and coatings, and it is also used as a reaction solvent in the manufacturing of pharmaceuticals, as well as in the production of lithium-ion batteries and electronic materials. However, NMP is known to have potential adverse health effects and environmental impacts, and as a result, its use is regulated in some regions.
Check Digit Verification of cas no
The CAS Registry Mumber 5550-33-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,5 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5550-33:
(6*5)+(5*5)+(4*5)+(3*0)+(2*3)+(1*3)=84
84 % 10 = 4
So 5550-33-4 is a valid CAS Registry Number.
