Check Digit Verification of cas no

The CAS Registry Mumber 31059-32-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,0,5 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 31059-32:
(7*3)+(6*1)+(5*0)+(4*5)+(3*9)+(2*3)+(1*2)=82
82 % 10 = 2
So 31059-32-2 is a valid CAS Registry Number.

Reactions of W(IV) diazoalkane complexes cis,mer- (X=Br, I; R=Me, Ph) and hydrazido(2-) complex cis,mer- with five equivalents of CH2X2 in toluene at 80 deg C gave paramagnetic W(V) complexes, mer,trans- and respectively.The latter complex was also obtained upon hydrolysis of a W(V) disilylhydrazido(2-) complex and was converted into mer,trans- by the subsequent condensation with RMeC=O.The structure of mer,trans- (6d) was determined by X-ray analysis.Crystal data for 6d are as follows: monoclinic, space group P21/n with a=9.900(3) Angstroem, b=21.029(4) Angstroem, c=13.950(2) Angstroem, β=96.80(2)o, V=2883.9(11) Angstroem3, Z=4 and R=0.060 for 4567 reflections.
