Check Digit Verification of cas no

The CAS Registry Mumber 103240-25-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,2,4 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 103240-25:
(8*1)+(7*0)+(6*3)+(5*2)+(4*4)+(3*0)+(2*2)+(1*5)=61
61 % 10 = 1
