Check Digit Verification of cas no

The CAS Registry Mumber 1257332-51-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,3,3 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1257332-51:
(9*1)+(8*2)+(7*5)+(6*7)+(5*3)+(4*3)+(3*2)+(2*5)+(1*1)=146
146 % 10 = 6
So 1257332-51-6 is a valid CAS Registry Number.
