Check Digit Verification of cas no

The CAS Registry Mumber 1256387-73-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,3,8 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1256387-73:
(9*1)+(8*2)+(7*5)+(6*6)+(5*3)+(4*8)+(3*7)+(2*7)+(1*3)=181
181 % 10 = 1
So 1256387-73-1 is a valid CAS Registry Number.
