97997-76-7 Usage
General Description
2,4,5,6-Tetramethylbenzenedisulfonyl dichloride is a white to off-white crystalline solid that is used as an intermediate in the production of dyes and other organic compounds. It is a highly reactive compound that is commonly used in organic synthesis, particularly in the formation of sulfonyl chlorides and sulfonyl chlorides. It is a strong electrophile and is often used in the modification of organic molecules. 2,4,5,6-Tetramethylbenzenedisulfonyl dichloride is also used as a reagent in the production of pharmaceuticals and agrochemicals, and is an important building block in the chemical industry. It should be handled with care, as it is corrosive and can cause severe skin and eye irritation.
Check Digit Verification of cas no
The CAS Registry Mumber 97997-76-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,9,9 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 97997-76:
(7*9)+(6*7)+(5*9)+(4*9)+(3*7)+(2*7)+(1*6)=227
227 % 10 = 7
So 97997-76-7 is a valid CAS Registry Number.
