369-65-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 369-65-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,6 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 369-65:
(5*3)+(4*6)+(3*9)+(2*6)+(1*5)=83
83 % 10 = 3
So 369-65-3 is a valid CAS Registry Number.

Synthesis of trifluoroethyl ethers from 2,2,2-trifluoroethyl chloride (HCFC-133a) in high temperature aqueous medium
Wu, Kai,Chen, Qing-Yun
, p. 79 - 83 (2007/10/03)
Treatment of 2,2,2-trifluoroethyl chloride (HCFC-133a) with alcohols (phenols) and aqueous KOH in autoclave at 240-280 C gives the corresponding 2,2,2-trifluoroethyl (2-chloro-1,1-difluoroethyl) ethers in good yields.
