6141-78-2

Tris(methylamido)thiophosphorus, also known as trimethylthiophosphoramide or PMT, is a phosphorus-containing organosulfur compound with the chemical formula (CH3N)3P=S. It is a colorless, crystalline solid that is sensitive to moisture and air. PMT is primarily used as a precursor in the synthesis of various organophosphorus compounds, including pesticides, flame retardants, and other specialty chemicals. Due to its reactivity, it is often handled under anhydrous conditions to prevent unwanted side reactions. The compound is also known for its potential applications in the development of new materials and pharmaceuticals, highlighting its importance in the field of organic chemistry.

6141-78-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6141-78-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,4 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6141-78:
(6*6)+(5*1)+(4*4)+(3*1)+(2*7)+(1*8)=82
82 % 10 = 2
So 6141-78-2 is a valid CAS Registry Number.
