76513-64-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76513-64-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,5,1 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 76513-64:
(7*7)+(6*6)+(5*5)+(4*1)+(3*3)+(2*6)+(1*4)=139
139 % 10 = 9
So 76513-64-9 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 (2007/10/02)
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.
