Check Digit Verification of cas no

The CAS Registry Mumber 2220-31-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,2 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2220-31:
(6*2)+(5*2)+(4*2)+(3*0)+(2*3)+(1*1)=37
37 % 10 = 7
So 2220-31-7 is a valid CAS Registry Number.

Tuning chemoselectivity in: O -/ N -arylation of 3-aryl-1,2,4-oxadiazolones with ortho -(trimethylsilyl)phenyl triflates via aryne insertion

Zhou, Lijing,Li, Hongji,Zhang, Wenge,Wang, Lei

, p. 4822 - 4825 (2018)

Herein, we first describe finely tunable chemoselectivity in arylation of 3-aryl-1,2,4-oxadiazolones with ortho-(trimethylsilyl)phenyl triflates, including O-arylation enabled by catalytic amount of silver nitrate and metal-free N-arylation. Both the arylation reactions can tolerate a series of functional groups, and afford the corresponding products in moderate to good yields.
