Preparation
a convenient one-pot procedure has been
developed by Kemp and Cowley in which trimethylsilylchloride
reacts with dichloromethane in the presence of nBuLi
at ?110°Cto give bis(trimethylsilyl)dichloromethane.1 This
intermediate is sequentially treated with nBuLi and ethanol
to yield chlorobis(trimethylsilyl)methane. A number of other
syntheses have been described
Check Digit Verification of cas no
The CAS Registry Mumber 5926-35-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,2 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5926-35:
(6*5)+(5*9)+(4*2)+(3*6)+(2*3)+(1*5)=112
112 % 10 = 2
So 5926-35-2 is a valid CAS Registry Number.
