Check Digit Verification of cas no

The CAS Registry Mumber 1449566-20-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,9,5,6 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1449566-20:
(9*1)+(8*4)+(7*4)+(6*9)+(5*5)+(4*6)+(3*6)+(2*2)+(1*0)=194
194 % 10 = 4
So 1449566-20-4 is a valid CAS Registry Number.

Facile synthesis of 3-substituted quinazoline-2,4-dione and 2,3-di-substituted quinazolinone derivatives

Farouk, Mahmoud,Alrokayan, Salman A.,Imran, Ahamad,Abu-Salah, Khalid M.,Ghazzali, Mohamed,Al-Farhan, Khalid A.,El-Gohary, Salem,Adly, Mamdouh

3-Substituted quinazoline-2,4(1H,3H)-dione and 2,3-di-substituted quinazolineone derivatives attract considerable interest due to their pharmacological properties. In this paper, we report the synthesis of N-substituted-3-nitrophthalimide derivatives II-III, the reactions of phthalimide III with amines, hydrazines, and amino acid derivatives to synthesise a small library of 3-substituted-5-nitroquinazoline-2,4(1H,3H)-diones IV-XIV and 2,3-di-substituted-6-nitro-quinazolineones XVIII-XIX.
