Check Digit Verification of cas no

The CAS Registry Mumber 1000-70-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,0 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1000-70:
20 % 10 = 0
So 1000-70-0 is a valid CAS Registry Number.

Catalytic conversion of isocyanates to carbodiimides by cyclopentadienyl manganese tricarbonyl and cyclopentadienyl iron dicarbonyl dimer

Rahman, A.K. Fazlur,Nicholas, Kenneth M.

, p. 6002 - 6004 (2007)

Isocyanates are catalytically converted to the corresponding carbodiimides in the presence of low valent transition metal complexes. The best conversions and yields were accomplished using [(C5R5)Fe(CO)2]2 (R = H or Me) or MeCpMn(CO)3 as catalysts.

Preparation and characterization of the disjoint diradical 4,4′-bis(1,2,3,5-dithiadiazolyl) [S2N2C-CN2S2] and its iodine charge transfer salt [S2N2C-CN2S2][I]


, p. 330 - 338 (1996)

Condensation of oxamidrazone with sulfur dichloride in acetonitrile affords 4,4′-bis(1,2,3,5-dithiadiazolium) dichloride in moderate yield. Reduction of this salt with triphenylantimony yields the diradical 4,4′-bis(1,2,3,5-dithiadiazolyl) [S2N2C-CN2S2], which has been isolated and characterized in the solid state as its dimer [S2N2C-CN2S2]2. The diradical is disjoint, and ab initio molecular orbital methods confirm a very small energy gap (3 at 273 K) of a simple five-line pattern (aN = 0.50 mT, g = 2.011), i.e., there is no observable exchange coupling between the two centers. In the solid state, the dimer [S2N2C-CN2S2]2 forms a slipped stack structure, with a mean intradimer S-S distance of 3.078 ? and mean interdimer S- - -S contact of 3.761 ?. Cosublimation of the diradical with iodine produces the charge-transfer salt [S2N2C-CN2S2][I], orthorhombic space group Ccmm, a = 11.909(3) ?, b = 3.271(2) ?, c = 19.860(6) ?, Z = 4 (at 293 K). In this structure the heterocyclic rings form perfectly superimposed and evenly spaced stacks along the y direction, with channels of disordered iodines. The iodine-doped material is metallic at ambient temperatures, with a single-crystal conductivity of 460 S cm-1 at 300 K; variable temperature conductivity and magnetic measurements reveal a phase transition near 270 K, with the onset of semiconducting behavior. Transport data for the neutral and doped materials are discussed in the light of Extended Hückel band calculations.
