Check Digit Verification of cas no
The CAS Registry Mumber 155632-41-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,6,3 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 155632-41:
(8*1)+(7*5)+(6*5)+(5*6)+(4*3)+(3*2)+(2*4)+(1*1)=130
130 % 10 = 0
So 155632-41-0 is a valid CAS Registry Number.

Synthesis of the First Thienothiophene Stabilized Only by Electronic Effects
Beye, Norbert,Cava, Michael P.
, p. 2223 - 2226 (1994)
The stable, crystalline 1,3-dibromo-4,6-dicyanothienothiophene (3a) has been synthesized.This is the first example of a thienothiophene stabilized solely by electronic effects.The dicarbomethoxy dibromo analog 3b and the tetrabromo analog 3c were also generated and found to be considerably less stable.
