(E)-2-(2-Methylphenyl)-1,2-diphenylvinyllithium is an organolithium compound characterized by its molecular formula C21H17Li and a molar mass of 290.24 g/mol. (E)-2-(2-Methylphenyl)-1,2-diphenylvinyllithium features a vinyl group (C=C) bonded to a lithium atom, with two phenyl rings and a 2-methylphenyl group attached to the vinyl carbon. The "E" configuration indicates that the two phenyl rings are on the same side of the double bond. It is a colorless solid, sensitive to air and moisture, and is commonly used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds and the synthesis of various aromatic compounds. Due to its high reactivity and sensitivity, it must be handled with care, typically under an inert atmosphere.

Check Digit Verification of cas no

The CAS Registry Mumber 78579-05-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,5,7 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78579-05:
(7*7)+(6*8)+(5*5)+(4*7)+(3*9)+(2*0)+(1*5)=182
182 % 10 = 2
So 78579-05-2 is a valid CAS Registry Number.
