72117-54-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72117-54-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,1,1 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 72117-54:
(7*7)+(6*2)+(5*1)+(4*1)+(3*7)+(2*5)+(1*4)=105
105 % 10 = 5
So 72117-54-5 is a valid CAS Registry Number.

Synthesis, spectroscopy and structure of phenylated cyclopentasilanes

P?schl, Ulrich,Siegl, Harald,Hassler, Karl

, p. 93 - 100 (2007/10/02)

Phenylated cyclopentasilanes Si5Ph10-nXn with X = OSO2CF3, F, Cl, Br, I or H and n = 1 or 2 were prepared in high yield by dearylation of Si5Ph10 with trifluoromethanesulphonic acid (CF3SO3H) and subsequent reaction with lithium or potassium halides and LiAlH4. The trans-1,3-isomers of Si5Ph8X2 were isolated by crystallization and the crystal structure of trans-1,3-difluorooctaphenyl- cyclopentasilane was determined. cis-1,3-, trans-1,2- and cis-1,2-Si5Ph8X2 were identified and characterized by 1H, 19F and 29Si NMR spectroscopy. Si-Si coupling constants were measured using INADEQUATE pulse sequences.
