Check Digit Verification of cas no

The CAS Registry Mumber 41652-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,6,5 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 41652-75:
(7*4)+(6*1)+(5*6)+(4*5)+(3*2)+(2*7)+(1*5)=109
109 % 10 = 9
So 41652-75-9 is a valid CAS Registry Number.

Nickel/Photo-Cocatalyzed Asymmetric Acyl-Carbamoylation of Alkenes

Fan, Pei,Lan, Yun,Zhang, Chang,Wang, Chuan

supporting information, p. 2180 - 2186 (2020/03/03)

An unprecedented asymmetric acyl-carbamoylation of pendant alkenes tethered on aryl carbamic chlorides with both aliphatic and aromatic aldehydes has been developed via the cooperative catalysis of a chiral nickel-PHOX complex and tetrabutylammonium decatungstate. This reaction represents the first example of merging hydrogen-atom-transfer photochemistry and asymmetric transition metal catalysis in difunctionalization of alkenes. Using this protocol, a variety of oxindoles bearing a challenging quaternary stereogenic center are furnished under mild conditions in highly enantioselective manner.
