Check Digit Verification of cas no

The CAS Registry Mumber 1259580-75-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,5,8 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1259580-75:
(9*1)+(8*2)+(7*5)+(6*9)+(5*5)+(4*8)+(3*0)+(2*7)+(1*5)=190
190 % 10 = 0
So 1259580-75-0 is a valid CAS Registry Number.
