Check Digit Verification of cas no

The CAS Registry Mumber 5105-39-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,0 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5105-39:
(6*5)+(5*1)+(4*0)+(3*5)+(2*3)+(1*9)=65
65 % 10 = 5
So 5105-39-5 is a valid CAS Registry Number.
