Hydroxyapatite Type I is a naturally occurring inorganic compound, primarily composed of calcium phosphate, with the chemical formula Ca10(PO4)6(OH)2. It is the main component of human bones and teeth, providing structural support and strength. This mineral is also found in various marine organisms, such as corals and shells. Due to its biocompatibility and osteoconductive properties, hydroxyapatite Type I is widely used in medical applications, including bone grafts, dental implants, and orthopedic surgeries. Its ability to promote bone growth and integrate with existing bone tissue makes it an essential material in the field of regenerative medicine.
The CAS Registry Mumber 130-66-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 0 respectively; the second part has 2 digits, 6 and 6 respectively. Calculate Digit Verification of CAS Registry Number 130-66: (5*1)+(4*3)+(3*0)+(2*6)+(1*6)=35 35 % 10 = 5 So 130-66-5 is a valid CAS Registry Number.
