89889-20-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89889-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,8 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89889-20:
(7*8)+(6*9)+(5*8)+(4*8)+(3*9)+(2*2)+(1*0)=213
213 % 10 = 3
So 89889-20-3 is a valid CAS Registry Number.

Preparation of (perfluoroalkyl)alkane thiols via Zemplén deacylation of fluorous (perfluoroalkyl)alkyl thioacetates

Menczinger, Bálint,Nemes, Anikó,Szíjjártó, Csongor,Rábai, József

, p. 70 - 77 (2018/03/21)

Convenient and robust synthesis of (perfluoroalkyl)alkane thiols [(CnF2n+1(CH2)mSH); m/n = 3/4,6,8,10, 4a-d; m/n = 2/6, 8; m/n = 1/1,2,3,7,8H, 12a-e] was developed starting from commercially available fluorous alcohols (1a-d, 5, 9a-e). The intermediate (perfluoroalkyl)alkyl iodides and/or sulfonates were reacted with potassium thioacetate in DMF, and the resulting thioacetates were deacetylated by a Zemplén analogue reaction. The (perfluoroalkyl)alkane thiols were obtained in good overall yields and high purity.

Fluorous dimethylthiocarbamate (FDMTC) protecting groups for alcohols

Kojima, Masaru,Nakamura, Yutaka,Ishikawa, Takuma,Takeuchi, Seiji

, p. 6309 - 6314 (2007/10/03)

N,N-Bis(perfluoroalkyl)thiocarbamoyl chlorides (FDMTC-Cls) were synthesized as reagent for the protection of alcohols. Using the crystalline FDMTC-Cls, the FDMTC groups were introduced into the alcohol molecules in excellent yields in the presence of sodium hydride in THF at room temperature. The products were separated from the excess alcohols by solid-phase extraction with a fluorous reverse-phase silica gel column (Fluorous Solid Phase Extraction; FSPE). The FDMTC groups were readily removed by oxidation with m-chloroperbenzoic acid (m-CPBA) and subsequent hydrolysis with KHCO3.
