7789-17-5 Usage

Description

Cesium iodide, with the chemical formula CsI, is a white, soft, and crystalline solid composed of cesium (Cs) and iodine (I). It is known for its high melting point and excellent transmission properties in the infrared region, making it a versatile and important chemical compound in various technological and scientific applications.

Uses

Used in Scintillation Detectors:
Cesium iodide is used as a scintillator in gamma-ray detectors for its high efficiency in converting gamma-ray photons into visible light, which can then be detected and measured.
Used in X-ray Imaging:
In the medical industry, cesium iodide serves as an intensifying screen in X-ray imaging, enhancing the contrast and resolution of the images by increasing the light output from the phosphor screen.
Used in Optical Materials:
Cesium iodide is utilized in the production of lenses, prisms, and windows for infrared detectors and spectrophotometers due to its excellent transmission properties in the infrared region.
Used in Night Vision Devices:
In the manufacturing of photocathodes for night vision devices, cesium iodide plays a crucial role in detecting low levels of light and converting it into an electrical signal for enhanced visibility in dark conditions.
Used in Photomultiplier Tubes:
Cesium iodide is employed in photomultiplier tubes for its high sensitivity in detecting low levels of light, making it suitable for various scientific and analytical applications that require precise light measurement.

Check Digit Verification of cas no

The CAS Registry Mumber 7789-17-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7789-17:
(6*7)+(5*7)+(4*8)+(3*9)+(2*1)+(1*7)=145
145 % 10 = 5
So 7789-17-5 is a valid CAS Registry Number.
