Check Digit Verification of cas no

The CAS Registry Mumber 5857-96-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,5 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5857-96:
(6*5)+(5*8)+(4*5)+(3*7)+(2*9)+(1*6)=135
135 % 10 = 5
So 5857-96-5 is a valid CAS Registry Number.
