Check Digit Verification of cas no

The CAS Registry Mumber 19689-08-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,6,8 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 19689-08:
(7*1)+(6*9)+(5*6)+(4*8)+(3*9)+(2*0)+(1*8)=158
158 % 10 = 8
So 19689-08-8 is a valid CAS Registry Number.

Synthesis and Insecticidal Efficacy of Novel Bis Quinazolinone Derivatives

Elshahawi, Manal M.,EL-Ziaty, Ahmed K.,Morsy, Jehan M.,Aly, Aly F.

, p. 1443 - 1448 (2016)

A novel bis benzoxazin-4-one derivative has been synthesized and utilized to construct a new series of bis quinazolin-4(3H)-one derivatives via the reactions with different nitrogen nucleophiles namely, primary amines (ammonia, ethanolamine, and 4-aminoantipyrine), secondary amines (morpholine and piperidine), diamine (o-phenylenediamine), hydrazine hydrate, and hydroxylamine. The insecticidal efficacy of newly synthesized compounds was also studied. The structural features of the synthesized compounds were assigned by spectral analysis.
