118718-73-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118718-73-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,7,1 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 118718-73:
(8*1)+(7*1)+(6*8)+(5*7)+(4*1)+(3*8)+(2*7)+(1*3)=143
143 % 10 = 3
So 118718-73-3 is a valid CAS Registry Number.

4-Alkoxy-6-alkyl-2-pyrones as Precursors for 4-Alkoxy-6-alkyl-2-aminobenzoic Acid Derivatives
Tam, Tim Fat,Coles, Peter
, p. 383 - 386 (2007/10/02)
4-Alkoxy-6-alkyl-2-pyrones undergo Diels-Alder reaction with dimethyl acetylenedicarboxylate to give dimethyl 4-alkoxy-6-alkylphthalates, which can be converted into 4-alkoxy-6-alkyl-2-aminobenzoic esters via a simple two-step sequence.
