Check Digit Verification of cas no

The CAS Registry Mumber 89209-41-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,2,0 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89209-41:
(7*8)+(6*9)+(5*2)+(4*0)+(3*9)+(2*4)+(1*1)=156
156 % 10 = 6
