780755-58-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 780755-58-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,8,0,7,5 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 780755-58:
(8*7)+(7*8)+(6*0)+(5*7)+(4*5)+(3*5)+(2*5)+(1*8)=200
200 % 10 = 0
So 780755-58-0 is a valid CAS Registry Number.

A facile synthetic route to monodisperse asymmetrical oligo(phenylene- ethynylene)s
Zhao, Jinling,Bo, Zhishan
, p. 1391 - 1402 (2007/10/03)
Monodisperse asymmetrical oligo(phenylene-ethynylene)s were synthesized iteratively by combining the selective deprotection and the Sonogashira coupling. Trimethylsilylethyl ester (TSE) and trimethylsilyl (TMS) were used as protecting groups for carboxyl
