[1,1'-Biphenyl]-4,4'-diamine sulphate is a chemical compound that serves as an intermediate in industrial chemistry. It is a sulfate salt of 4,4'-Biphenyldiamine, characterized by two phenyl rings connected by a two-atom chain. The biphenyl component, which consists of two benzene rings, provides the compound with stability, while the diamine group offers strong bonding potential. This combination makes it a versatile agent in the synthesis of other chemicals. However, it is important to note that prolonged exposure can lead to eye irritation and skin sensitivity, and environmental considerations must be taken into account when disposing of this substance to minimize its potential impact on aquatic life.

Check Digit Verification of cas no

The CAS Registry Mumber 21136-70-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,3 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21136-70:
(7*2)+(6*1)+(5*1)+(4*3)+(3*6)+(2*7)+(1*0)=69
69 % 10 = 9
So 21136-70-9 is a valid CAS Registry Number.
