Check Digit Verification of cas no

The CAS Registry Mumber 1248587-19-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,8,5,8 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1248587-19:
(9*1)+(8*2)+(7*4)+(6*8)+(5*5)+(4*8)+(3*7)+(2*1)+(1*9)=190
190 % 10 = 0
So 1248587-19-0 is a valid CAS Registry Number.

Bromophilic substitution/carbophilic substitution cascade reactions of α,α-dibromo-2-methoxyacetophenone with C-, N- and O-nucleophiles

Tatar, Jovana,Markovi?, Rade,Stojanovi?, Milovan,Baranac-Stojanovi?, Marija

experimental part, p. 4851 - 4855 (2010/10/02)

α,α-Dibromo-2-methoxyacetophenone reacts, under mild reaction conditions, with C-, N- and O-nucleophiles via a bromophilic substitution/protonation/carbophilic substitution cascade process to afford α-monosubstituted-2-methoxyacetophenones in moderate to good yield. The only exception from this reaction pathway is the reaction with the anion derived from malononitrile in which 2-aroyl-1,1,3,3-tetracyanopropene is obtained.
