Check Digit Verification of cas no

The CAS Registry Mumber 181305-63-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,3,0 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 181305-63:
(8*1)+(7*8)+(6*1)+(5*3)+(4*0)+(3*5)+(2*6)+(1*3)=115
115 % 10 = 5
So 181305-63-5 is a valid CAS Registry Number.

Direct Acetoxylation of Arenes

Hong Nguyen, Thi Anh,Hou, Duen-Ren

supporting information, p. 8127 - 8131 (2021/08/23)

Acetoxylation of arenes is an important reaction and an unmet need in chemistry. We report a metal-free, direct acetoxylation reaction using sodium nitrate under an anhydrous environment of trifluoroacetic acid, acetic acid, and acetic anhydride. Arenes (31 examples), with oxidation potentials (Eox, in V vs SCE) lower than benzene (2.48 V), were acetoxylated with good yields and regioselectivity. A stepwise, single electron-transfer mechanism is proposed.
