7559-53-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7559-53-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,5 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7559-53:
(6*7)+(5*5)+(4*5)+(3*9)+(2*5)+(1*3)=127
127 % 10 = 7
So 7559-53-7 is a valid CAS Registry Number.

Enantioselective Copper-Catalyzed Electrophilic Sulfenylation of Cyclic Imino Esters

Chen, Zhiwei,Lin, Huaxin,Han, Jian,Fang, Dongmei,Wang, Min,Liao, Jian

supporting information, p. 9146 - 9150 (2021/11/30)

Herein we report an enantioselective sulfenylation of cyclic imino esters with the efficient and versatile sulfenylation reagent S-alkyl 4-methylbenzenesulfonothioates. By utilizing the Cu/tBu-Phosferrox catalytic system, we can assemble diverse S-alkyl groups into the cyclic imino esters under mild conditions in good yields and with excellent enantioselectivities. Remarkably, this method demonstrates a high tolerance of diverse functional groups and proves to be applicable in the late-stage functionalization of pharmaceuticals.
