Check Digit Verification of cas no

The CAS Registry Mumber 1190225-25-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,2,2 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1190225-25:
(9*1)+(8*1)+(7*9)+(6*0)+(5*2)+(4*2)+(3*5)+(2*2)+(1*5)=122
122 % 10 = 2
So 1190225-25-2 is a valid CAS Registry Number.
