73019-17-7 Usage
General Description
N,N''-naphthalene-1,5-diylbis[N',N'-dimethylurea], also known as NDPU, is a chemical compound primarily used as a catalyst for the production of polyurethane foam. It acts as a blowing agent, helping to create the foam structure by releasing gases during the foam-forming reaction. NDPU is a white, crystalline solid that is soluble in organic solvents. It is known for its high thermal stability and low reactivity, making it a suitable additive for polyurethane foam production. NDPU is also used as a crosslinking agent for coatings and adhesives, as well as a curing agent for epoxy resins. It is important to handle NDPU with care and follow safety guidelines, as it may be harmful if ingested or inhaled and can cause skin and eye irritation.
Check Digit Verification of cas no
The CAS Registry Mumber 73019-17-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,0,1 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 73019-17:
(7*7)+(6*3)+(5*0)+(4*1)+(3*9)+(2*1)+(1*7)=107
107 % 10 = 7
So 73019-17-7 is a valid CAS Registry Number.
