Check Digit Verification of cas no
The CAS Registry Mumber 488-86-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,8 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 488-86:
(5*4)+(4*8)+(3*8)+(2*8)+(1*6)=98
98 % 10 = 8
So 488-86-8 is a valid CAS Registry Number.

Page/Page column 14, (2010/11/25)
The present invention provides in one aspect a composition having at least one croconine derivative. This composition may be disposed on a semiconductor layer which is further disposed on an electrically conductive surface to provide a dye-sensitized electrode. The dye-sensitized electrode can be assembled together with a counter electrode and a redox electrolyte to provide a photovoltaic cell. The photovoltaic cell may be used as a single cell or in tandem with other cells.

Page/Page column 6, (2008/06/13)
Croconic acid or a salt thereof is easily produced at low cost by a reaction of a hydrocarbon compound consisting of a five-membered ring or a hydrocarbon compound consisting of a five-membered ring having an oxo group and/or a monovalent group linked via an oxygen atom with a halogenating agent.
The photochemistry of the rhodizonate dianion in aqueous solution
Iraci, G.,Back, M. H.
, p. 1293 - 1294 (2007/10/02)
The photochemistry of the rhodizonate dianion at 483 nm has been studied in aqueous solution at pH 8.3.In the absence of oxygen no reaction was observed.In the presence of oxygen, 6.2 x 10-5 M, the dianion was consumed with a quantum yield of 0.044.The oxidation apparently did not involve the formation of O2(1Δg).Electron transfer from the excited dianion was observed with methyl viologen.
