Check Digit Verification of cas no

The CAS Registry Mumber 1205743-65-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,5,7,4 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1205743-65:
(9*1)+(8*2)+(7*0)+(6*5)+(5*7)+(4*4)+(3*3)+(2*6)+(1*5)=132
132 % 10 = 2
