Check Digit Verification of cas no

The CAS Registry Mumber 75256-31-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,5 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 75256-31:
(7*7)+(6*5)+(5*2)+(4*5)+(3*6)+(2*3)+(1*1)=134
134 % 10 = 4
So 75256-31-4 is a valid CAS Registry Number.
