Check Digit Verification of cas no

The CAS Registry Mumber 1129683-21-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,9,6,8 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1129683-21:
(9*1)+(8*1)+(7*2)+(6*9)+(5*6)+(4*8)+(3*3)+(2*2)+(1*1)=161
161 % 10 = 1
