Check Digit Verification of cas no

The CAS Registry Mumber 1146897-25-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,6,8,9 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1146897-25:
(9*1)+(8*1)+(7*4)+(6*6)+(5*8)+(4*9)+(3*7)+(2*2)+(1*5)=187
187 % 10 = 7
So 1146897-25-7 is a valid CAS Registry Number.
