Check Digit Verification of cas no

The CAS Registry Mumber 1257259-87-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,2,5 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1257259-87:
(9*1)+(8*2)+(7*5)+(6*7)+(5*2)+(4*5)+(3*9)+(2*8)+(1*7)=182
182 % 10 = 2
So 1257259-87-2 is a valid CAS Registry Number.
