Check Digit Verification of cas no

The CAS Registry Mumber 66962-38-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,9,6 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 66962-38:
(7*6)+(6*6)+(5*9)+(4*6)+(3*2)+(2*3)+(1*8)=167
167 % 10 = 7
So 66962-38-7 is a valid CAS Registry Number.

Crystal and molecular structure of imidazole derivatives with different substituents

Devarajegowda,Prasad, J. Shashidhara,Sridhar,Abdoh

, p. 317 - 330 (2000)

The crystal and molecular structures of 1-Methyl-2-Isopropyl-5-Nitroimidazole (A) and 1-Methyl-2(Thiophenyl)-Methyl-5-Nitroimidazole (B) derivatives were determined by X-ray diffraction methods. The compound A, C7H11N3O2, crystallises in the monoclinic space group P21/c with a = 9.9582(2) angstrom, b = 6.5240(4) angstrom, c = 13.5560(3) angstrom, β = 99.8930(17)°, V = 867.6(5) angstrom3, Z = 4, Dcalc = 1.295 Mg/m3, μ = 0.813 mm-1, F000 = 360, CuKα = 1.5406 angstrom and R = 0.09. The five membered ring with two nitrogen atoms is planar. Layering is observed down a and b axes. The compound B, C11H11N3O2S, crystallises in the triclinic space group P1 with a = 6.270(10) angstrom, b = 27.874(12) angstrom, c = 12.960(3) angstrom, α = 90°, β = 89.90°, γ = 90°, V = 2266(35) angstrom3, Z = 8, Dcalc = 1.461 Mg/m3, μ = 2.504 mm-1, F000 = 1040, CuKα = 1.5406 angstrom and R = 0.11.
