Check Digit Verification of cas no
The CAS Registry Mumber 144865-58-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,8,6 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 144865-58:
(8*1)+(7*4)+(6*4)+(5*8)+(4*6)+(3*5)+(2*5)+(1*8)=157
157 % 10 = 7
So 144865-58-7 is a valid CAS Registry Number.

Synthesis of polymetallacycloalkanes
Mazerolles, Pierre,Laurent, Christian
, p. 115 - 125 (2007/10/02)
In the reduction of a mixture of an organosilicon or organogermanium dihalide and 1,4-dibromo-2,3-bis(bromomethyl)-2-butene with an alkali metal forming hexahydrodimetallapentalenes, best yields were obtained by using lithium in ether/tetrahydrofuran.This reaction, when extended to 1,2-dichloro-disilanes and -digermanes gave the corresponding tetrametallaoctahydronaphthalenes.When activated zinc was used instead of alkali metal in these reactions, bis(methylene)metallacycloalkanes were formed; their reactions with germanium diiodide gave bicyclic compounds with two or three metal atoms per molecule.A stepwise reaction gave chains of organogermanium bicyclic compounds of controlled length.
