Check Digit Verification of cas no

The CAS Registry Mumber 15968-05-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,9,6 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 15968-05:
(7*1)+(6*5)+(5*9)+(4*6)+(3*8)+(2*0)+(1*5)=135
135 % 10 = 5
So 15968-05-5 is a valid CAS Registry Number.

METHOD FOR SEPARATING AND CLEANING UP POLYHALOGENATED BIPHENYLS

-

Page/Page column 26-28, (2008/06/13)

The method for separating and cleaning up polyhalogenated biphenyls (PHBs) is characterized by comprising the following three steps: (1) the step of bringing a sample containing PHBs into contact with a fibrous activated carbon; (2) the step of washing the fibrous activated carbon with hexanes; and (3) the step of eluting PHBs from the fibrous activated carbon.

Structural Studies of Some 2,6(2',6')-Halogen-Substituted Biphenyl Derivatives

Field, Leslie D.,Skelton, Brian W.,Sternhell, Sever,White, Allan H.

, p. 391 - 399 (2007/10/02)

Single-crystal X-ray structure determinations have been carried out at 295 K on a number of biphenylderivatives substituted with chlorine or bromine in the 2- and 6-positions in order to ascertain the effect of substitution on the torsion angle about the central bond. 2,2',6,6'-Tetrachlorobiphenyl, (1), is orthorhombic, P nca, a 12.35(1), b 10.521(7), c 9.390(8) Angstroem, Z 4; the structure was refined to a residual of R 0.040 for No 528 independent 'observed' reflections.The interplanar dihedral angle, θ, is 81.7 deg. 4'-Bromo-2,4,6-trichlorobiphenyl, (2), is monoclinic, C2/c, a 19.27(1), b 7.940(2), c 33.315(8) Angstroem, β 90.93(6) deg, Z 16; R 0.036 for No 1795 with θ 84.3 and 80.6 deg for the two independent molecules. 2,2',4,4',6,6'-Hexabromobiphenyl, (3), is orthorhombic, P nca, a 14.48(1), b 12.71(1), c 8.534(7) Angstroem; R 0.044 for No 693 with θ 83.0 deg. 2,4,4',6-Tetrabromobiphenyl, (4), is triclinic, P1, with a 8.14(1), b 10.74(2), c 35.42(4) Angstroem, α 87.87(10), β 79.39(10) deg, Z 8; R 0.049 for No 3962, with θ 89.8, 80.7, 86.9, 83.6 deg, for the four independent molecules.Steric interactions between the substituents ortho to the central inter-ring bond are not the sole determinant of the geometry of these compounds in the solid state.The pairs (1) and (3), and (2) and (4), are pseudoisostructural in each case.
