Check Digit Verification of cas no
The CAS Registry Mumber 128011-03-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,1 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128011-03:
(8*1)+(7*2)+(6*8)+(5*0)+(4*1)+(3*1)+(2*0)+(1*3)=80
80 % 10 = 0
So 128011-03-0 is a valid CAS Registry Number.

SYNTHESIS OF 1-ALKYNYLBICYCLOPENTANES
Bunz, Uwe,Szeimies, Guenter
, p. 2087 - 2088 (1989)
Radical chain addition of 1,1,1-trichloroethane and, respectively, 1,1-dichloroethane to -propellane led to bicyclopentane derivatives 5 and 6 which could be converted by sodium amide into the acetylenes 9 and 10.Glaser type coupling afforded the diacetylenes 12 and 13.
