Check Digit Verification of cas no

The CAS Registry Mumber 80436-20-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,3 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 80436-20:
(7*8)+(6*0)+(5*4)+(4*3)+(3*6)+(2*2)+(1*0)=110
110 % 10 = 0
So 80436-20-0 is a valid CAS Registry Number.

Studies on Quinones. VII(1). Synthesis of Some Benzothiophene-4,7-diones

Ruiz, V. M.,Tapia, R.,Valderrama, J.,Vega, J. C.

, p. 1161 - 1164 (2007/10/02)

The synthesis of methyl 4,7-dihydro-4,7-dioxobenzothiophene-2-carboxylate (20) based on the reaction of methyl mercaptoacetate with activated 1,4-benzoquinones is described.Methyl 4,7-dihydro-4,7-dioxo-5-hydroxybenzothiophene-2-carboxylate (24) and its corresponding methyl ether 26 were obtained through a Thiele-Winter acetoxylation on 20.On the basis of the properties of methyl 4,7-dihydro-4,7-dioxo-6-methoxybenzothiophene-2-carboxylate (21) obtained from 2,4,5-trimethoxybenzaldehyde (32), the structures of the products 24 and 26 are proposed.
