863763-87-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 863763-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,3,7,6 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 863763-87:
(8*8)+(7*6)+(6*3)+(5*7)+(4*6)+(3*3)+(2*8)+(1*7)=215
215 % 10 = 5
So 863763-87-5 is a valid CAS Registry Number.

Interaction of 3-(2-Aminophenyl)-6-R1-1,2,4-triazin-5-ones with Acylating Reagents: An Efficient Method for Preparation of 6-Substituted 3-R1-2H-[1,2,4]triazino[2,3-c]quinazolin-2-ones

, p. 776 - 783 (2016)

The series of 6-substituted 3-R1-2H-[1,2,4]triazino[2,3-c]quinazolin-2-one was prepared via condensation of 3-(2-aminophenyl)-6-R1-1,2,4-triazin-5-ones with acylating reagents. Particularities of 1H NMR spectra have been also discussed based on the comparison of experimental and theoretical results for 3-methyl-6-phenyl-2H-[1,2,4]triazino[2,3-c]quinazolin-2-one and its 4,3-isomer.
