Check Digit Verification of cas no

The CAS Registry Mumber 105817-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,8,1 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 105817-91:
(8*1)+(7*0)+(6*5)+(5*8)+(4*1)+(3*7)+(2*9)+(1*1)=122
122 % 10 = 2
So 105817-91-2 is a valid CAS Registry Number.

Low Coordinated Phosphorus Compounds, 54. - Phosphaalkenes via Cope Rearrangement

Appel, Rolf,Winkhaus, Volker,Knoch, Falk

, p. 125 - 130 (2007/10/02)

The styryl-substituted diphosphanes 2a, b are prepared by the reaction of the chlorophosphanes 1a, b with magnesium or tert-butyllithium, respectively.Compound 2b, substituted with bulky residues, gives the racemic form of the phosphaalkene 5 by Cope rearrangement, which is slowly and irreversibly converted into the meso-form.
