Check Digit Verification of cas no

The CAS Registry Mumber 91823-23-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,2 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 91823-23:
(7*9)+(6*1)+(5*8)+(4*2)+(3*3)+(2*2)+(1*3)=133
133 % 10 = 3
So 91823-23-3 is a valid CAS Registry Number.

Synthesis and characterization of fluorescent nitrobenzoyl polythiophenes

Coelho, Elaine C.S.,Nascimento, Valberes B.,Ribeiro, Adriana S.,Navarro, Marcelo

, p. 134 - 143 (2015)

Two thiophene derivatives named 4"-nitrobenzoyl (thiophene-3′-yl)-1-ethylate (NTh) and 3",5"-dinitrobenzoyl (thiophene-3′-yl)-1-ethylate (DNTh) were synthesized and characterized. Both monomers were electrochemically polymerized onto platinum or glassy ca
