Check Digit Verification of cas no

The CAS Registry Mumber 1021178-07-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,1,7 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1021178-07:
(9*1)+(8*0)+(7*2)+(6*1)+(5*1)+(4*7)+(3*8)+(2*0)+(1*7)=93
93 % 10 = 3
