Check Digit Verification of cas no

The CAS Registry Mumber 125440-15-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,4,4 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 125440-15:
(8*1)+(7*2)+(6*5)+(5*4)+(4*4)+(3*0)+(2*1)+(1*5)=95
95 % 10 = 5
So 125440-15-5 is a valid CAS Registry Number.
