Check Digit Verification of cas no

The CAS Registry Mumber 18869-04-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,6 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18869-04:
(7*1)+(6*8)+(5*8)+(4*6)+(3*9)+(2*0)+(1*4)=150
150 % 10 = 0
So 18869-04-0 is a valid CAS Registry Number.

On Organophosphorus Compounds, XXII. 1,2-Diaryl-1,2-dibromodiphosphanes

Hinke, Axel,Kuchen, Wilhelm

, p. 3003 - 3010 (2007/10/02)

1,2-Diaryl-1,2-dibromodiphosphanes R(Br)P-P(Br)R 2 (R = C6H5; 4-XC6H4, X = CH3O, F, Cl) were prepared by dehalogenation of RPBr2 with magnesium in a one-batch procedure.While solid 2 presumably consists of only one diastereomer there exists an equilibrium between meso-2, rac-2 and their disproportionation products RPBr2 and (RP)5 in solutions of 2.The influence of temperature, R and solvent on this equilibrium was investigated. - The reaction products of the dissolved phenyl compound 2a correspond to a reaction of its disproportionation products PhPBr2 and (PhP)5, the former preferably reacting on nucleophilic substitution, the latter with electrophilic agents.Under heterogenous conditions diphosphanes Ph(R)P-P(R)Ph can be obtained from 2a and LiR.
