Check Digit Verification of cas no

The CAS Registry Mumber 121881-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,8,8 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121881-25:
(8*1)+(7*2)+(6*1)+(5*8)+(4*8)+(3*1)+(2*2)+(1*5)=112
112 % 10 = 2
So 121881-25-2 is a valid CAS Registry Number.
