50998-72-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 50998-72-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,9,9 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 50998-72:
(7*5)+(6*0)+(5*9)+(4*9)+(3*8)+(2*7)+(1*2)=156
156 % 10 = 6
So 50998-72-6 is a valid CAS Registry Number.

A CONVENIENT SYNTHESIS OF NITRONES BY N-ALKYLATION OF O-TRIMETHYLSILYLOXIMES
LeBel, Norman A.,Balasubramanian, N.
, p. 4331 - 4334 (2007/10/02)
Aldoxime and ketoxime-O-trimethylsilyl ethers can be alkylated with trialkyl-oxonium tetrafluoroborates and alkyl triflates at or below room temperature to produce nitrones in good yields.
