Check Digit Verification of cas no

The CAS Registry Mumber 59790-57-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,7,9 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 59790-57:
(7*5)+(6*9)+(5*7)+(4*9)+(3*0)+(2*5)+(1*7)=177
177 % 10 = 7
So 59790-57-7 is a valid CAS Registry Number.

Regioselective Synthesis and Polymerization of Substituted o-Trimethylsilylphenylacetylenes

Yamaguchi, Masahiko,Tsukamoto, Yukiharu,Ikeura, Chinatsu,Nakamura, Shigeo,Minami, Toru

, p. 1259 - 1262 (2007/10/02)

Substituted o-trimethylsilylphenylacetylenes were synthesized by o-metalation of phenylacetylenes with complex reagent of butyllithium and t-BuOK, and were polymerized in the presence of a tungsten catalyst giving deeply colored poly(arylacetylene)s.Relationship between the structure of monomers and polymers was examined.
