404888-68-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 404888-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,4,8,8 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 404888-68:
(8*4)+(7*0)+(6*4)+(5*8)+(4*8)+(3*8)+(2*6)+(1*8)=172
172 % 10 = 2
So 404888-68-2 is a valid CAS Registry Number.

Preparation and structural characterization of bis[tris(trimethylsilyl)-germyl]zinc, [(Me3Si)3Ge]2Zn

Nanjo, Masato,Oda, Takashi,Mochida, Kunio

, p. 1261 - 1264 (2003)

Bis[tris(trimethylsilyl)germyl]zinc, [(Me3Si)3Ge]2Zn, was prepared by the reaction of [tris(trimethylsilyl)germyl]lithium, (Me3Si)3GeLi(thf), with zinc chloride, ZnCl2, and by the reaction of tris(trimethylsilyl)germane, (Me3Si)3GeH, with diethylzinc, Et2Zn. The molecular structure of [(Me3Si)3Ge]2Zn was determined by spectroscopic and X-ray diffraction methods. In [(Me3Si)3Ge]2Zn, the two tris(trimethylsilyl)germyl ligands, (Me3Si)3Ge, are bonded in a linear fashion to the zinc atom and are staggered with respect to each other. The reactions of bis(germyl)zinc with substrates were also examined.
