Check Digit Verification of cas no

The CAS Registry Mumber 5120-36-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,2 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5120-36:
(6*5)+(5*1)+(4*2)+(3*0)+(2*3)+(1*6)=55
55 % 10 = 5
So 5120-36-5 is a valid CAS Registry Number.
