14950-49-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 14950-49-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,9,5 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 14950-49:
(7*1)+(6*4)+(5*9)+(4*5)+(3*0)+(2*4)+(1*9)=113
113 % 10 = 3
So 14950-49-3 is a valid CAS Registry Number.

β-(Trimethylsilyl)ethoxymethyl chloride. A new reagent for the protection of the hydroxyl group
Lipshutz, Bruce H.,Pegram, Joseph J.
, p. 3343 - 3346 (1980)
Reactions of β-(trimethylsilyl)ethoxymethyl chloride with alcohols afford the corresponding ethers in high yield. Deprotection using n-Bu4NF in THF or HMPA cleanly regenerates the hydroxyl function.
