Description
Strontium Iodate, with the chemical formula Sr(IO3)2, is a compound that exists in two forms: monohydrate (Sr(IO3)2·H2O) and hexahydrate (Sr(IO3)2·6H2O). It is characterized by its solubility properties, with the monohydrate having a solubility product of 3.77×10^-7 and the hexahydrate with a slightly higher value of 4.55×10^-7. The hexahydrate form is a crystalline powder that is slightly soluble in water but becomes soluble in dilute nitric acid, forming the nitrate plus iodine. Its solubility in water increases with temperature, being 0.19 g/100 ml at 20°C and 0.35 g/100 ml at 100°C. Strontium Iodate also exhibits magnetic susceptibility, with a value of 108 g/10^-6 cm^3/mol. It can be synthesized by reacting iodic acid with strontium carbonate, resulting in either the monohydrate or hexahydrate form, similar to its calcium counterpart.

Check Digit Verification of cas no
The CAS Registry Mumber 13470-01-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,7 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13470-01:
(7*1)+(6*3)+(5*4)+(4*7)+(3*0)+(2*0)+(1*1)=74
74 % 10 = 4
So 13470-01-4 is a valid CAS Registry Number.
