Check Digit Verification of cas no

The CAS Registry Mumber 942066-38-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,2,0,6 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 942066-38:
(8*9)+(7*4)+(6*2)+(5*0)+(4*6)+(3*6)+(2*3)+(1*8)=168
168 % 10 = 8
So 942066-38-8 is a valid CAS Registry Number.

Synthesis of chiral γ-sultams through intramolecular reductive amination with sulfonylcarbamate as N-source

Song, Bo,Ji, Yue,Hu, Shu-Bo,Yu, Chang-Bin,Zhou, Yong-Gui

supporting information, p. 1528 - 1530 (2017/03/23)

An efficient and enantioselective palladium-catalyzed intramolecular asymmetric reductive amination with sulfonylcarbamates as N-sources was reported, providing a facile and general access to the chiral γ-sultam derivatives with up to 97% of enantioselect

Highly enantioselective Pd-catalyzed asymmetric hydrogenation of activated imines

Wang, You-Qing,Lu, Sheng-Mei,Zhou, Yong-Gui

, p. 3729 - 3734 (2008/02/04)

(Chemical Equation Presented) Pd/bisphosphines complexes are highly effective catalysts for asymmetric hydrogenation of activated imines in trifluoroethanol. The asymmetric hydrogenation of N-diphenylphosphinyl ketimines 3 with Pd(CF3CO2)/(S)-SegPhos indicated 87-99% ee, and N-tosylimines 5 could gave 88-97% ee with Pd-(CF3CO 2)/(S)-SynPhos as a catalyst. Cyclic N-sulfonylimines 7 and 11 were hydrogenated to afford the useful chiral sultam derivatives in 79-93% ee, which are important organic synthetic intermediates and structural units of agricultural and pharmaceutical agents.
