Pentafluoroethanethiol, also known as 1,1,2,2,2-pentafluoroethyl methyl sulfide or C2H3FS5, is a colorless, volatile, and highly toxic liquid with a pungent odor. It is an organosulfur compound and a derivative of ethane, where one hydrogen atom is replaced by a methyl group and all other hydrogen atoms are replaced by fluorine atoms. Pentafluoroethanethiol is used as a reagent in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals, as well as in the production of specialty polymers. Due to its high reactivity and toxicity, it requires careful handling and storage.

1540-78-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1540-78-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,4 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.Calculate Digit Verification of CAS Registry Number 1540-78:
(6*1)+(5*5)+(4*4)+(3*0)+(2*7)+(1*8)=69
69 % 10 = 9
So 1540-78-9 is a valid CAS Registry Number.
