Weddellite, also known as whewellite, is a calcium oxalate mineral that forms as a result of the oxidation of organic matter. It is commonly found in the form of small, colorless to white crystals and is often associated with urinary and kidney stones. Due to its insolubility in water and organic solvents, weddellite is difficult to dissolve and remove from the body. It is also used in the production of various calcium oxalate-based products and can be found in caves as a result of bacterial degradation of organic matter. Furthermore, weddellite is known for its potential role in the deterioration of cultural heritage sites, particularly limestone structures.

7236-42-2 Usage
Uses
Used in Pharmaceutical Industry:Weddellite is used as a raw material for the production of calcium oxalate-based pharmaceutical products, which can be used to treat conditions related to calcium oxalate crystals in the body.
Used in Cultural Heritage Preservation:
Weddellite is used as a target for conservation efforts aimed at preventing the deterioration of limestone structures and cultural heritage sites caused by the mineral's formation and growth.
Used in Chemical Research:
Weddellite is used as a subject of study in chemical research to better understand its properties, formation processes, and potential applications in various industries.
Used in Environmental Science:
Weddellite is used as an indicator of bacterial activity and organic matter degradation in natural environments, such as caves, where it can form as a result of these processes.
Check Digit Verification of cas no
The CAS Registry Mumber 7236-42-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,3 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.Calculate Digit Verification of CAS Registry Number 7236-42:
(6*7)+(5*2)+(4*3)+(3*6)+(2*4)+(1*2)=92
92 % 10 = 2
So 7236-42-2 is a valid CAS Registry Number.
