7721-01-9 Usage
General Description
Tantalum(V) chloride, also known as tantalum pentachloride, is a chemical compound with the formula TaCl5. It appears as a white to light yellow crystalline powder or lumps and has a molar mass of 358.213 g/mol. It is moisture-sensitive, noncombustible, and decomposes when heated to produce toxic and corrosive fumes. Tantalum(V) chloride is used as a catalyst in various chemical reactions, in the manufacture of other chemicals, and in the field of materials science for the production of special glass or ceramics. Tantalum(V) chloride is harmful if swallowed, inhaled, or gets in contact with skin and eyes, so proper protective measures should be taken when handling it.
Check Digit Verification of cas no
The CAS Registry Mumber 7721-01-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,2 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7721-01:
(6*7)+(5*7)+(4*2)+(3*1)+(2*0)+(1*1)=89
89 % 10 = 9
So 7721-01-9 is a valid CAS Registry Number.

, p. 207 - 212 (1989)
The successful preparation of Ta2S2C at 1150°C has been found to be intimately linked to the presence of halogens in the reaction. Adventitious chlorine obtained either through the use of excess carbon or of graphite crucibles was ap
