Check Digit Verification of cas no

The CAS Registry Mumber 675120-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,5,1,2 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 675120-59:
(8*6)+(7*7)+(6*5)+(5*1)+(4*2)+(3*0)+(2*5)+(1*9)=159
159 % 10 = 9
So 675120-59-9 is a valid CAS Registry Number.

Some reactions and spectroscopic studies of tris(pentafluorophenyl) arsenic and -antimony(III and V) derivatives

Shukla, Sanjeev K.,Ranjan, Ashok,Saxena

, p. 165 - 170 (2003)

The reactions of tris(pentafluorophenyl)arsenic(III) with iodine monochloride, iodine monoazide, and dithiocyanogen yielded corresponding oxidative-addition products of the type (C6F5) 3As(V)XY (X=I, Y=Cl, N3; X=Y=NCS). The elemental sulphur also added oxidatively with tris(pentafluorophenyl)arsenic(III) yielding tris(pentafluorophenyl)arsine(V) sulphide. Some displacement reactions were also carried out to synthesize mixed pseudohalide derivatives of the type (C6F5)3 M(N3)NCS (M=As and Sb) and their insertion reactions were studied with phenyl isothiocyanate which yielded the corresponding 1,2-cycloaddition products, i.e. tetrazole-5-thiones. The compounds were characterized by elemental analysis, molar conductance, UV, IR and 19F NMR spectroscopic studies.
