Check Digit Verification of cas no

The CAS Registry Mumber 91667-67-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,6 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 91667-67:
(7*9)+(6*1)+(5*6)+(4*6)+(3*7)+(2*6)+(1*7)=163
163 % 10 = 3
