132639-44-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132639-44-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,6,3 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 132639-44:
(8*1)+(7*3)+(6*2)+(5*6)+(4*3)+(3*9)+(2*4)+(1*4)=122
122 % 10 = 2
So 132639-44-2 is a valid CAS Registry Number.

Bis(bis(trimethylsilyl)phosphino)silan 2SiH2 und 1,2-Bis(bis(trimethylsilyl)phosphino)disilan 2
Hassler, K.,Katzenbeisser, U.
, p. C18 - C20 (1990)
The compounds H2Si2 and 2 were prepared and characterized by 29Si NMR, 31P NMR, IR and Raman spectroscopy.After thermolysis of these compounds no cyclic silylphosphanes could be detected in the reaction mixture, although this did contain P(SiMe3)3.
