Magnesium, chloro[(2-propenyloxy)methyl]-, also known as chloromethyl(2-propenyloxy)magnesium, is an organomagnesium compound with the chemical formula C4H7ClMgO. It is a colorless, highly reactive liquid that is sensitive to air and moisture. Magnesium, chloro[(2-propenyloxy)methyl]- is primarily used as a reagent in organic synthesis, particularly in the formation of Grignard reagents, which are crucial for various carbon-carbon bond-forming reactions. Due to its high reactivity, it must be handled under an inert atmosphere, such as nitrogen or argon, to prevent unwanted side reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 821-49-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 821-49:
(5*8)+(4*2)+(3*1)+(2*4)+(1*9)=68
68 % 10 = 8
So 821-49-8 is a valid CAS Registry Number.
