N,N'-dinitroso-N,N'-diphenyl-benzidine (DNDB) is a chemical compound that is widely recognized for its application as a rubber antioxidant and stabilizer in the production of industrial rubber products. It is characterized by its yellow crystalline solid form, a strong yet pleasant odor, and its high insolubility in water. Despite its utility in the rubber industry, DNDB is also known for its high reactivity, which can lead to the formation of highly toxic and carcinogenic nitrosamines when it comes into contact with strong acids or alkaline substances. This characteristic necessitates careful handling, protective measures, and proper disposal to prevent potential health hazards and environmental contamination.

Check Digit Verification of cas no
The CAS Registry Mumber 40317-17-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,1 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.Calculate Digit Verification of CAS Registry Number 40317-17:
(7*4)+(6*0)+(5*3)+(4*1)+(3*7)+(2*1)+(1*7)=77
77 % 10 = 7
So 40317-17-7 is a valid CAS Registry Number.
