Check Digit Verification of cas no

The CAS Registry Mumber 189632-58-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,6,3 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 189632-58:
(8*1)+(7*8)+(6*9)+(5*6)+(4*3)+(3*2)+(2*5)+(1*8)=184
184 % 10 = 4
So 189632-58-4 is a valid CAS Registry Number.

New type of polysilanes: Poly(1,1-silole)s

Tamao, Kohei,Yamaguchi, Shigehiro

, p. 5 - 11 (2000)

Poly(1,1-silole)s were synthesized for the first time in 1999, by us and by West and his coworkers, as a new type of polysilane which is expected to have a low-lying LUMO due to the σ*-π*conjugation characteristic of the silole ring. Summarized herein are the development of new synthetic methodologies and the structural aspects, photophysical properties and a unique reactivity of the resulting oligo- and poly(1,1-silole)s.
