Check Digit Verification of cas no

The CAS Registry Mumber 1029435-25-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,9,4,3 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1029435-25:
(9*1)+(8*0)+(7*2)+(6*9)+(5*4)+(4*3)+(3*5)+(2*2)+(1*5)=133
133 % 10 = 3
So 1029435-25-3 is a valid CAS Registry Number.
