As bis-trimethylsilylated N-methylhydroxylamine N-Methyl-N,O-bis(trimethylsilyl)-
hydroxylamine can convert
aldehydes and ketones to N-methyl nitrones with regio- and
chemoselectivity; source of methylnitrene by pyrolysis;
source of the trimethylsilyl(methyl)aminyl radical by photolysis.

It is obtained in 52% yield by reaction of Nmethylhydroxylamine
with chlorotrimethylsilane (2.0 equiv)
and triethylamine (3.3 equiv) in ether at 25 °C.
Check Digit Verification of cas no
The CAS Registry Mumber 22737-33-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,7,3 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 22737-33:
(7*2)+(6*2)+(5*7)+(4*3)+(3*7)+(2*3)+(1*3)=103
103 % 10 = 3
So 22737-33-3 is a valid CAS Registry Number.
