Check Digit Verification of cas no

The CAS Registry Mumber 190902-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,9,0 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 190902-19:
(8*1)+(7*9)+(6*0)+(5*9)+(4*0)+(3*2)+(2*1)+(1*9)=133
133 % 10 = 3
