Check Digit Verification of cas no

The CAS Registry Mumber 874126-49-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,1,2 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 874126-49:
(8*8)+(7*7)+(6*4)+(5*1)+(4*2)+(3*6)+(2*4)+(1*9)=185
185 % 10 = 5
So 874126-49-5 is a valid CAS Registry Number.

Synthesis and characterization of low generation halogenated linear poly(arylpropargyl)ether (PAPE) branches via selective palladium catalyzed coupling reactions

L'Hermite, Nathalie,Peyrat, Jean-Fran?ois,Alami, Mouad,Brion, Jean-Daniel

, p. 8987 - 8991 (2005)

A rapid convergent synthesis of first- and second-generation halogenated linear poly(arylpropargyl ether) branches 7 and 10 is described. The key step of the sequence studied involves a selective Sonogashira-Linstrumelle (S-L) cross-coupling reaction of a
