Check Digit Verification of cas no

The CAS Registry Mumber 74767-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,6 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74767-50:
(7*7)+(6*4)+(5*7)+(4*6)+(3*7)+(2*5)+(1*0)=163
163 % 10 = 3
