Check Digit Verification of cas no

The CAS Registry Mumber 1202576-49-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,5,7 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1202576-49:
(9*1)+(8*2)+(7*0)+(6*2)+(5*5)+(4*7)+(3*6)+(2*4)+(1*9)=125
125 % 10 = 5
So 1202576-49-5 is a valid CAS Registry Number.
