604800-36-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 604800-36-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,0,4,8,0 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 604800-36:
(8*6)+(7*0)+(6*4)+(5*8)+(4*0)+(3*0)+(2*3)+(1*6)=124
124 % 10 = 4
So 604800-36-4 is a valid CAS Registry Number.

Synthesis of alkoxy-substituted ortho-phenylene ethynylene oligomers
Jones, Ticora V.,Blatchly, Richard A.,Tew, Gregory N.
, p. 3297 - 3299 (2003)
(Matrix presented) This Letter describes the first published synthesis and characterization of alkoxy-substituted ortho-phenylene ethynylene (o-PE) oligomers. Sonogashira coupling was used to assemble discrete chain lengths, using a key monomer with ortho
