Check Digit Verification of cas no

The CAS Registry Mumber 1620197-94-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,1,9 and 7 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1620197-94:
(9*1)+(8*6)+(7*2)+(6*0)+(5*1)+(4*9)+(3*7)+(2*9)+(1*4)=155
155 % 10 = 5
