Tenorite, also known as lead(II) oxide (PbO), is a reddish-brown, insoluble powder that is a common chemical compound used in various applications. It is primarily used as a pigment in paints, ceramics, and glass, as well as in the production of lead-acid batteries. Tenorite is also employed as a catalyst in the chemical industry and as an additive in rubber and plastics. However, due to its toxicity and potential environmental and health risks, its use has been restricted or replaced with safer alternatives in many applications.
The CAS Registry Mumber 1317-92-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,1 and 7 respectively; the second part has 2 digits, 9 and 2 respectively. Calculate Digit Verification of CAS Registry Number 1317-92: (6*1)+(5*3)+(4*1)+(3*7)+(2*9)+(1*2)=66 66 % 10 = 6 So 1317-92-6 is a valid CAS Registry Number.
