Check Digit Verification of cas no
The CAS Registry Mumber 18146-62-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,4 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18146-62:
(7*1)+(6*8)+(5*1)+(4*4)+(3*6)+(2*6)+(1*2)=108
108 % 10 = 8
So 18146-62-8 is a valid CAS Registry Number.

Molten and Solid Trialkylsulfonium Iodides and Their Polyiodides as Electrolytes in Dye-Sensitized Nanocrystalline Solar Cells
Paulsson, Helene,Hagfeldt, Anders,Kloo, Lars
, p. 13665 - 13670 (2003)
The overall solar-to-electric energy conversion efficiencies in solar simulators, and the incident monochromatic photon-to-current-efficiencies (IPCE) was measured for a selection of molten salt electrolytes to reveal their possible use as electrolytes in dye-sensitized nanocrystalline solar cells (DNSC). The IPCE results of (Et2MeS)I and (Bu2MeS)I were stable above 55% from 400 to 550 nm and then decreased on the red side of the spectra. The addition of iodine to (Bu2MeS)I and (Bu2EtS)I indicated increasing IPCE values at 520-540 nm; from 55 to 60% and 38 to 46%, respectively. (Te2MeS)I, (Bu2MeS)I, and (Bu2EtS)I showed good conducting abilities at ambient conditions and provided good light-to-electricity conversion efficiencies while used as electrolytes in DNSC. The liquid electrolytes (Et2MeS)I provided the highest conversion efficiencies at room temperature.
