Check Digit Verification of cas no

The CAS Registry Mumber 1256271-80-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,2,7 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1256271-80:
(9*1)+(8*2)+(7*5)+(6*6)+(5*2)+(4*7)+(3*1)+(2*8)+(1*0)=153
153 % 10 = 3
So 1256271-80-3 is a valid CAS Registry Number.
