Check Digit Verification of cas no

The CAS Registry Mumber 81257-93-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,5 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81257-93:
(7*8)+(6*1)+(5*2)+(4*5)+(3*7)+(2*9)+(1*3)=134
134 % 10 = 4
So 81257-93-4 is a valid CAS Registry Number.
