Check Digit Verification of cas no

The CAS Registry Mumber 1209526-25-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,9,5,2 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1209526-25:
(9*1)+(8*2)+(7*0)+(6*9)+(5*5)+(4*2)+(3*6)+(2*2)+(1*5)=139
139 % 10 = 9
So 1209526-25-9 is a valid CAS Registry Number.
