Check Digit Verification of cas no

The CAS Registry Mumber 3290-56-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,9 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3290-56:
(6*3)+(5*2)+(4*9)+(3*0)+(2*5)+(1*6)=80
80 % 10 = 0
So 3290-56-0 is a valid CAS Registry Number.
