90055-51-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90055-51-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,5 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90055-51:
(7*9)+(6*0)+(5*0)+(4*5)+(3*5)+(2*5)+(1*1)=109
109 % 10 = 9
So 90055-51-9 is a valid CAS Registry Number.

Enantioselective α-Chlorination Reactions of in Situ Generated C1 Ammonium Enolates under Base-Free Conditions

Stockhammer, Lotte,Weinzierl, David,B?gl, Thomas,Waser, Mario

, p. 6143 - 6147 (2021/08/18)

The asymmetric α-chlorination of activated aryl acetic acid esters can be carried out with high levels of enantioselectivities utilizing commercially available isothiourea catalysts under base-free conditions. The reaction, which proceeds via the in situ formation of chiral C1 ammonium enolates, is best carried out under cryogenic conditions combined with a direct trapping of the activated α-chlorinated ester derivative to prevent epimerization, thus allowing for enantioselectivities of up to e.r. 99:1.
