Triphenyl-(4-trimethylsilanyl-but-3-ynyl)-phosphonium; iodide is a complex organic compound with the chemical formula C27H28PSiI. It is a phosphonium salt, which consists of a phosphonium cation (triphenyl-(4-trimethylsilanyl-but-3-ynyl)-phosphonium) and an iodide anion. The compound features a phosphorus atom bonded to three phenyl groups and a 4-trimethylsilanyl-but-3-ynyl group, which is a butynyl group with a trimethylsilyl substituent. The iodide anion is present to balance the positive charge of the phosphonium cation. Triphenyl-(4-trimethylsilanyl-but-3-ynyl)-phosphonium; iodide is often used in organic synthesis, particularly in the formation of carbon-carbon bonds and as a reagent in various chemical reactions. Its unique structure, with the trimethylsilanyl group, provides it with specific reactivity and stability properties that can be exploited in the synthesis of complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 41345-58-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,3,4 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 41345-58:
(7*4)+(6*1)+(5*3)+(4*4)+(3*5)+(2*5)+(1*8)=98
98 % 10 = 8
So 41345-58-8 is a valid CAS Registry Number.

The esters R[C≡C]2·CH2·CH= CH·[CH2]7·CO2Me{R=Me[CH 2]2, MeC≡C, cis- or trans-MeCH=CH, trans-HO·CH2·CH=CH, HO·CH 2·C≡C, cis- or trans-MeO2C·CH=CH, MeO2C·C≡C, (EtO)2CH, OHC, or H 2N·OC} were prepared from the Wittig salt Me 3Si·C=C·CH2·CH2· P+Ph3|- via |C≡C·CH2·CH= CH·[CH2]7·CO2Me; several were specifically labelled [at C(9), C(17), and C(18)]. The Wittig salt offers a general route to 1-ene-4,6-diyne and more highly unsaturated skipped en-yne systems.
