Check Digit Verification of cas no

The CAS Registry Mumber 1256294-99-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,2,9 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1256294-99:
(9*1)+(8*2)+(7*5)+(6*6)+(5*2)+(4*9)+(3*4)+(2*9)+(1*9)=181
181 % 10 = 1
So 1256294-99-1 is a valid CAS Registry Number.
