Check Digit Verification of cas no

The CAS Registry Mumber 31793-58-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,7,9 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 31793-58:
(7*3)+(6*1)+(5*7)+(4*9)+(3*3)+(2*5)+(1*8)=125
125 % 10 = 5
So 31793-58-5 is a valid CAS Registry Number.

Synthesis and biological evaluation of some 3H-quinazolin-4-one derivatives

Sharaf, Afrah,Ragab, Sherif Shaban,Elbarbary, Ahmed A.,Shaban, Elkhabiry,El Sayed, Ibrahim El Tantawy

, p. 291 - 302 (2022)

Starting from 3-phenylquinazoline-2,4(1H,3H)-dithione, some new derivatives of 3H-quinazoline-4-ones were synthesized. The structures of all new compounds were inferred based on the mass spectral, infrared, and NMR spectral data as well as the elemental analytical data. Some compounds were chosen for testing their biological activities as antibacterial, antifungal, and anticancer agents. Graphic abstract: [Figure not available: see fulltext.]
