Zircon (ZrSiO?) and iron coral (a form of iron oxide, Fe?O?) are two distinct chemical substances with unique properties and applications. Zircon, a naturally occurring mineral, is known for its high refractive index and strong dispersion, making it a valuable material in the production of ceramics, abrasives, and gemstones. It is also used as a source of zirconium, a metal with applications in nuclear reactors and various industrial processes. Iron coral, on the other hand, is a reddish-brown iron oxide that forms in marine environments and is often used as a pigment in paints and coatings due to its vibrant color. It also has applications in the construction industry as a component in concrete and as a natural iron supplement in agriculture. Both substances, though different in composition and uses, contribute significantly to various industries and human activities.

Check Digit Verification of cas no

The CAS Registry Mumber 68187-13-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,1,8 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 68187-13:
(7*6)+(6*8)+(5*1)+(4*8)+(3*7)+(2*1)+(1*3)=153
153 % 10 = 3
So 68187-13-3 is a valid CAS Registry Number.
