Ethylsulfonyl diazomethane, also known as ethylsulfonyl methylidene, is a chemical compound with the formula (CH3SO2)2CHN2. It is a yellow, crystalline solid that is highly reactive and toxic. ethylsulfonyl diazomethane is primarily used as a reagent in organic synthesis, particularly for the formation of carbon-carbon bonds and the conversion of carboxylic acids to esters. Ethylsulfonyl diazomethane is synthesized by the reaction of ethylsulfonyl chloride with diazomethane, and it is known for its ability to form stable ylides, which are useful in various chemical transformations. Due to its hazardous nature, it is essential to handle ethylsulfonyl diazomethane with extreme caution and in a controlled environment.

Check Digit Verification of cas no

The CAS Registry Mumber 2849-65-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,4 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2849-65:
(6*2)+(5*8)+(4*4)+(3*9)+(2*6)+(1*5)=112
112 % 10 = 2
So 2849-65-2 is a valid CAS Registry Number.
