Check Digit Verification of cas no

The CAS Registry Mumber 1240940-55-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,9,4 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1240940-55:
(9*1)+(8*2)+(7*4)+(6*0)+(5*9)+(4*4)+(3*0)+(2*5)+(1*5)=129
129 % 10 = 9
So 1240940-55-9 is a valid CAS Registry Number.

experimental part, p. 1355 - 1362 (2010/04/26)

New soluble poly(p-phenylenevinylene) derivatives with 1,3,4-oxadiazole and pyrazole rings along the main chain were synthesized by Heck coupling. The new conjugated polymers are soluble in common organic solvents as a result of the fully conjugated backb
