Check Digit Verification of cas no

The CAS Registry Mumber 220463-45-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,4,6 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 220463-45:
(8*2)+(7*2)+(6*0)+(5*4)+(4*6)+(3*3)+(2*4)+(1*5)=96
96 % 10 = 6
