145624-64-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 145624-64-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,6,2 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 145624-64:
(8*1)+(7*4)+(6*5)+(5*6)+(4*2)+(3*4)+(2*6)+(1*4)=132
132 % 10 = 2
So 145624-64-2 is a valid CAS Registry Number.

Geminal bis(sulfoximine)s: Synthesis and applications in asymmetric catalysis

Reggelin,Weinberger,Spohr

, p. 1295 - 1306 (2007/10/03)

A number of C2-symmetrical geminal bis-(sulfoximine)s have been prepared for the first time and used as ligands in boron-mediated reductions of acetophenone and copper complex-catalyzed 1,4-additions of diethylzinc to 2-cyclohexenone. The coppe

One-pot synthesis of (S)-4-isopropyl-2-p-toluene-4,5-dihydro-[1.2λ6,3]oxathiazole 2-Oxides: Efficient precursors of optically active sulfoximines

Reggelin, Michael,Weinberger, Heinz

, p. 6959 - 6962 (2007/10/02)

The title compounds were prepared from p-toluenesulfinyl chloride and (S)-O-trimethylsilyl valinol without isolation of intermediates. Key step in the synthesis is the fluoride-induced cyclisation of sulfonimidoyl chlorides yielding the crystalline sulfon
