Check Digit Verification of cas no

The CAS Registry Mumber 202070-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,0,7 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 202070-75:
(8*2)+(7*0)+(6*2)+(5*0)+(4*7)+(3*0)+(2*7)+(1*5)=75
75 % 10 = 5
