Check Digit Verification of cas no

The CAS Registry Mumber 135-53-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 135-53:
(5*1)+(4*3)+(3*5)+(2*5)+(1*3)=45
45 % 10 = 5
So 135-53-5 is a valid CAS Registry Number.
