Check Digit Verification of cas no

The CAS Registry Mumber 1748-00-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,4 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1748-00:
(6*1)+(5*7)+(4*4)+(3*8)+(2*0)+(1*0)=81
81 % 10 = 1
So 1748-00-1 is a valid CAS Registry Number.

Selective synthesis of halosilanes from hydrosilanes and utilization for organic synthesis

Kunai, Atsutaka,Ohshita, Joji

, p. 3 - 15 (2007/10/03)

Selective synthesis of halosilanes has been examined. Various types of halosilanes and halohydrosilanes, such as R3SiX, R2SiHX, R2SiX2, RSiH2X, RSiHX2 (X=Cl, Br, F), were obtained by the reactions of the corresponding hydrosilanes with Cu(II)-based reagents selectively in high yields. This method could be also applied to the synthesis of chlorofluorosilanes and chlorohydrogermanes. On the other hand, iodo- and bromosilanes and germanes were obtained by Pd- or Ni-catalyzed hydride-halogen exchange reactions of hydrosilanes with alkyl or allyl halides. Their synthetic applications have been demonstrated by using iodo- and bromosilanes and chlorofluorosilanes.
