Check Digit Verification of cas no
The CAS Registry Mumber 415949-88-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,5,9,4 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 415949-88:
(8*4)+(7*1)+(6*5)+(5*9)+(4*4)+(3*9)+(2*8)+(1*8)=181
181 % 10 = 1
So 415949-88-1 is a valid CAS Registry Number.

Synthesis of 2-alkoxymethyl-3-trifluoromethyl-1,4-naphthoquinones
Van Tuyen, Nguyen,Kesteleyn, Bart,De Kimpe, Norbert
, p. 121 - 127 (2007/10/03)
2-Alkoxymethyl-3-trifluoromethyl-1,4-naphthoquinones were conveniently synthesized in two steps by treatment of 2-substituted-3-bromo-1,4-dimethoxynaphthalene with CF3COONa/CuI and subsequent dealkylative oxidation by treatment with cerium(IV) ammonium nitrate.
