Check Digit Verification of cas no

The CAS Registry Mumber 24648-09-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,6,4 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 24648-09:
(7*2)+(6*4)+(5*6)+(4*4)+(3*8)+(2*0)+(1*9)=117
117 % 10 = 7
So 24648-09-7 is a valid CAS Registry Number.

2,4,6,8,9,10-Hexachlor-2,4,6,8,9,10-hexaboradamantan

Haubold, Wolfgang,Keller, Willi,Sawitzki, Gisela

, p. 19 - 26 (1989)

The pyrolysis of alkyldichloroboranes such as MeBCl2, Cl2BCH=CHBCl2, Cl2BCH2BCl2 or (Cl2B)3CH at 450 deg C leads to the formation of hexachloro-hexaboraadamantane, C4H4B6Cl6 (I).The structure - determined by X-ray diffraction - and the spectroscopic data of 2,4,6,8,9,10-hexachloro-2,4,6,8,9,10-hexaboradamantane are in agreement with the classical description as an organoborane, rather than as a molecule with a carborane framework.Substitution reactions are described.The bromo compound C4H4B6Br6 can be prepared by heating Me2BBr or MeBBr2 to 520 deg C.
