General Description
Lead(II) oxide, also known as lead monoxide, is a chemical compound with the formula PbO. It is a yellowish or reddish crystalline solid that is insoluble in water. Lead(II) oxide is commonly used as a pigment in paints, ceramic glazes, and glass. It is also used in the manufacturing of lead-acid batteries and as a radiation shield in some nuclear reactors.

Due to its toxicity, the use of lead(II) oxide is being phased out in many applications and replaced with safer alternatives.
Check Digit Verification of cas no
The CAS Registry Mumber 1335-25-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,3 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1335-25:
(6*1)+(5*3)+(4*3)+(3*5)+(2*2)+(1*5)=57
57 % 10 = 7
