144205-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144205-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,2,0 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 144205-40:
(8*1)+(7*4)+(6*4)+(5*2)+(4*0)+(3*5)+(2*4)+(1*0)=93
93 % 10 = 3
So 144205-40-3 is a valid CAS Registry Number.

Synthese 1,4-disubstituierter Tetrasilane durch selektive Spaltung von Si-Phenyl-Bindungen
Stueger, Harald
, p. 11 - 19 (2007/10/02)
Just two of three SiPh bonds per silicon atom are cleaved by excess HBr under pressure.Thus, pentaphenyldisilane reacts with HBr at room temperature to give 1-phenyl-2,2,3,3-tetrabromodisilane.Subsequent coupling with bis-(t-butyl)-mercury yields, 1,4-dip
