Check Digit Verification of cas no

The CAS Registry Mumber 1417894-71-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,8,9 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1417894-71:
(9*1)+(8*4)+(7*1)+(6*7)+(5*8)+(4*9)+(3*4)+(2*7)+(1*1)=193
193 % 10 = 3
