(4-methyl-1,2,5,6-tetrahydrobenzoyl)triphenylethoxycarbonylmethylenephosphorane is a complex organic compound with the molecular formula C37H33O3P. It is a phosphorus-containing reagent used in organic synthesis, particularly in the formation of carbon-carbon bonds through the Wittig reaction. This reaction involves the conversion of aldehydes or ketones into olefins, which are essential components in the synthesis of various organic compounds. The structure of (4-methyl-1,2,5,6-tetrahydrobenzoyl)triphenylethoxycarbonylmethylenephosphorane consists of a phosphorane core, with a triphenylethyl group attached to the phosphorus atom, and a 4-methyl-1,2,5,6-tetrahydrobenzoyl group connected to the carbonyl carbon. Its unique structure allows it to act as a strong nucleophile, facilitating the formation of new carbon-carbon double bonds in the presence of carbonyl compounds. This reagent is valuable in the synthesis of complex organic molecules, such as natural products and pharmaceuticals, due to its ability to introduce double bonds in a controlled and selective manner.

Check Digit Verification of cas no

The CAS Registry Mumber 85426-41-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,4,2 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 85426-41:
(7*8)+(6*5)+(5*4)+(4*2)+(3*6)+(2*4)+(1*1)=141
141 % 10 = 1
So 85426-41-1 is a valid CAS Registry Number.
