Check Digit Verification of cas no

The CAS Registry Mumber 952190-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,2,1,9 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 952190-12:
(8*9)+(7*5)+(6*2)+(5*1)+(4*9)+(3*0)+(2*1)+(1*2)=164
