(4-Methylphenylethinyl)triphenylphosphonium-bromid is a complex organic compound with the chemical formula C29H26BrP. It is a phosphonium salt, characterized by the presence of a phosphonium cation (P+) and a bromide anion (Br-). The phosphonium cation consists of a central phosphorus atom bonded to three phenyl rings and a 4-methylphenylethinyl group, which is an ethynyl group (C≡CH) attached to a 4-methylphenyl ring. (4-Methylphenylethinyl)triphenylphosphonium-bromid is often used in organic synthesis and as a reagent in various chemical reactions due to its unique structure and properties. It is also known for its potential applications in the field of materials science, particularly in the development of conductive polymers and other advanced materials.

Check Digit Verification of cas no

The CAS Registry Mumber 86429-39-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,4,2 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 86429-39:
(7*8)+(6*6)+(5*4)+(4*2)+(3*9)+(2*3)+(1*9)=162
162 % 10 = 2
So 86429-39-2 is a valid CAS Registry Number.
