Check Digit Verification of cas no

The CAS Registry Mumber 51043-75-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,0,4 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 51043-75:
(7*5)+(6*1)+(5*0)+(4*4)+(3*3)+(2*7)+(1*5)=85
85 % 10 = 5
So 51043-75-5 is a valid CAS Registry Number.
