Check Digit Verification of cas no

The CAS Registry Mumber 1297593-97-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,7,5,9 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1297593-97:
(9*1)+(8*2)+(7*9)+(6*7)+(5*5)+(4*9)+(3*3)+(2*9)+(1*7)=225
225 % 10 = 5
So 1297593-97-5 is a valid CAS Registry Number.
