Check Digit Verification of cas no

The CAS Registry Mumber 128405-06-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,0 and 5 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128405-06:
(8*1)+(7*2)+(6*8)+(5*4)+(4*0)+(3*5)+(2*0)+(1*6)=111
111 % 10 = 1
So 128405-06-1 is a valid CAS Registry Number.

The Synthesis of 2,11-Diamino-4,9-diphenyl-4,9-dihydrobenzo [f] pyrano[3,2-h]chromene-3,10-dicarbonitrile Derivatives using Triethanolammonium Acetate as a Green Ionic Liquid

Khazaei, Ardeshir,Bashirian, Ehsan,Ranjbaran, Azam,Khazaei, Marzieh,Moosavi-Zare, Ahmad Reza

, p. 757 - 763 (2017/07/25)

Triethanolammonium acetate [TEA][HOAc] was used as a green ionic liquid and successfully utilized for the multi-component synthesis of 2,11-diamino-4,9-diphenyl-4,9-dihydrobenzo[f]pyrano[3,2-h]chromene-3,10-dicarbonitrile derivatives as new compounds by the reaction of 2,3-naphthalenediol with malononitrile and various aldehydes. Mild reaction conditions and high yields are some of the advantages of this method. These compounds were identified by IR, NMR spectroscopy and mass analysis.
