Check Digit Verification of cas no

The CAS Registry Mumber 3209-78-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,0 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3209-78:
(6*3)+(5*2)+(4*0)+(3*9)+(2*7)+(1*8)=77
77 % 10 = 7
So 3209-78-7 is a valid CAS Registry Number.
