Check Digit Verification of cas no

The CAS Registry Mumber 65038-18-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,0,3 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 65038-18:
(7*6)+(6*5)+(5*0)+(4*3)+(3*8)+(2*1)+(1*8)=118
118 % 10 = 8
So 65038-18-8 is a valid CAS Registry Number.

Photoredox-Catalyzed α-Aminoalkylcarboxylation of Allenes with CO2

Hahm, Hyungwoo,Baek, Doohyun,Kim, Dowon,Park, Seongwook,Ryoo, Jeong Yup,Hong, Sukwon

supporting information, p. 3879 - 3884 (2021/05/29)

The photoredox-catalyzed α-aminoalkylcarboxylation of aryl allenes with CO2 and N,N-dimethylanilines is reported for the first time (26 examples, up to 96% yield). In the case of electron-deficient allenes, good regioselectivity was observed (up to 94:6), exclusively generating kinetic products over thermodynamic products. This protocol is a novel synthetic method for highly functionalized β,γ-unsaturated γ-aminobutyric esters.
