13817-22-6 Usage
General Description
Casteinlaudite is a rare mineral that was first discovered in the Nickenich quarry in Germany. It is a complex sodium-calcium borosilicate mineral with the chemical formula NaCaMg_2(BO_3)_2(Si_2O_7)F. It typically occurs as small, colorless to white prismatic crystals and is often found in association with other borosilicate minerals such as danburite and wadalite. Casteinlaudite has a very high hardness and is not easily soluble in acids. It is primarily used for research and mineral collection purposes due to its rarity and unique crystal structure.
Check Digit Verification of cas no
The CAS Registry Mumber 13817-22-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,1 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13817-22:
(7*1)+(6*3)+(5*8)+(4*1)+(3*7)+(2*2)+(1*2)=96
96 % 10 = 6
So 13817-22-6 is a valid CAS Registry Number.
