Check Digit Verification of cas no

The CAS Registry Mumber 143366-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,3,6 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143366-19:
(8*1)+(7*4)+(6*3)+(5*3)+(4*6)+(3*6)+(2*1)+(1*9)=122
122 % 10 = 2
So 143366-19-2 is a valid CAS Registry Number.

A convenient synthesis of methyl 1-alkoxy-3-perfluoroalkyl-2-naphthoates

Ding,Pu,Zhang

, p. 635 - 637 (2007/10/02)

Methyl 1-alkoxy-3-perfluoroalkyl-2-naphthoates 5 were synthesized by heating appropriately substituted 2-triphenylphosphoranylidene-2-butenoates 3 in xylenes at 250°C in a sealed tube. Compounds 3 were obtained via an intramolecular Wittig reaction of 2-alkoxycarbonylbenzyltriphenylphosphonium bromide (1) with methyl 2-perfluoroalkynoates 2 in the presence of potassium carbonate.
