Check Digit Verification of cas no

The CAS Registry Mumber 109788-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,8 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109788-30:
(8*1)+(7*0)+(6*9)+(5*7)+(4*8)+(3*8)+(2*3)+(1*0)=159
