Check Digit Verification of cas no

The CAS Registry Mumber 129047-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,4 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129047-33:
(8*1)+(7*2)+(6*9)+(5*0)+(4*4)+(3*7)+(2*3)+(1*3)=122
122 % 10 = 2
