Check Digit Verification of cas no

The CAS Registry Mumber 1640-54-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1640-54:
(6*1)+(5*6)+(4*4)+(3*0)+(2*5)+(1*4)=66
66 % 10 = 6
So 1640-54-6 is a valid CAS Registry Number.

A convenient approach to 2,4-disubstituted quinazoline-3-oxides using active MnO2 as the oxidant

Ye, Xinglin,Chen, Zhiyuan,Zhang, Zhipeng,Fu, Yang,Deng, Zhihong,Peng, Yiyuan

supporting information, p. 682 - 689 (2019/09/06)

Using cheap, readily available, and economic active MnO2 as an oxidant, a series of 2,4-disubstituted quinazoline-3-oxides were synthesized in good to excellent yields by oxidation of the corresponding 1,2-dihydroquinazoline-3-oxides under mild
