General Description
[1,1'-Biphenyl]-4,4'-diamine, N,N'-bis(4-aminophenyl)-N,N'-diphenyl- is a chemical compound that is commonly referred to as 4,4'-diaminodiphenylmethane (MDA). It is a diamine compound that is primarily used in the production of polyurethane foams, resins, and elastomers. MDA is a key intermediate in the production of several important industrial chemicals and products. It is also used in the manufacture of pharmaceuticals, dyes, and pigments. However, it is important to note that MDA is classified as a potential human carcinogen and exposure to this compound should be carefully controlled and monitored in industrial and manufacturing settings.
Check Digit Verification of cas no
The CAS Registry Mumber 155557-65-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,5,5 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 155557-65:
(8*1)+(7*5)+(6*5)+(5*5)+(4*5)+(3*7)+(2*6)+(1*5)=156
156 % 10 = 6
So 155557-65-6 is a valid CAS Registry Number.
