Check Digit Verification of cas no

The CAS Registry Mumber 1283774-46-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,3,7,7 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1283774-46:
(9*1)+(8*2)+(7*8)+(6*3)+(5*7)+(4*7)+(3*4)+(2*4)+(1*6)=188
188 % 10 = 8
So 1283774-46-8 is a valid CAS Registry Number.

One-pot synthesis of 2-amino-5,10-dihydro-5,10-dioxo-4-phenyl-4h-benzo[g] chromene derivatives catalyzed by ZnCl2

Srinivas,Rao, V. Rajeswar

, p. 806 - 811 (2011)

An efficient one-pot synthesis of 2-amino-5,10-dihydro-5,10-dioxo-4-phenyl- 4H-benzo[g]chromene derivatives has been achieved by the reaction of 2-hydroxynaphthalene-1,4-dione, cyanothioacetamide, and aromaticaldehyde in EtOH at room temperature catalyzed by ZnCl2. The structures of the products were characterized by infrared, 1H NMR, mass, and elemental analysis.
