49805-26-7 Usage
General Description
Benzenemethanesulfonyl cyanide is a chemical compound with the formula C8H7NO2S. It is a white solid at room temperature and is insoluble in water. It is commonly used as a reagent in organic synthesis, particularly in the preparation of sulfonamides and related compounds. It is also a valuable intermediate in the production of pharmaceuticals and agrochemicals. Benzenemethanesulfonyl cyanide is a highly reactive compound and should be handled with caution, as it is a powerful irritant to the eyes and skin. It is also toxic if ingested or inhaled, so proper safety precautions should be taken when working with it.
Check Digit Verification of cas no
The CAS Registry Mumber 49805-26-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,8,0 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 49805-26:
(7*4)+(6*9)+(5*8)+(4*0)+(3*5)+(2*2)+(1*6)=147
147 % 10 = 7
So 49805-26-7 is a valid CAS Registry Number.
