N-Tosyl-glyoxylimidsaeure-aethylester-hydrazon, also known as N-tosyl-glyoxylyl imidazolidine-2-yl ethyl ester hydrazone, is a complex organic compound with the chemical formula C12H16N2O4S. It is a derivative of glyoxylic acid, featuring an imidazolidine-2-yl ethyl ester group and a tosyl (tosylate) group. -hydrazon is used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the activation of aldehydes and ketones. It serves as a masked form of glyoxylic acid, providing a convenient way to introduce a glyoxylate group into various organic molecules. The hydrazone functionality allows for selective reactions and can be used to control the reactivity of the glyoxylic acid moiety, making it a valuable tool in the synthesis of complex organic molecules and natural products.

Check Digit Verification of cas no

The CAS Registry Mumber 2845-33-2 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 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2845-33:
(6*2)+(5*8)+(4*4)+(3*5)+(2*3)+(1*3)=92
92 % 10 = 2
So 2845-33-2 is a valid CAS Registry Number.
