Check Digit Verification of cas no

The CAS Registry Mumber 1644563-00-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,4,5,6 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1644563-00:
(9*1)+(8*6)+(7*4)+(6*4)+(5*5)+(4*6)+(3*3)+(2*0)+(1*0)=167
