Check Digit Verification of cas no

The CAS Registry Mumber 5914-60-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,1 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5914-60:
(6*5)+(5*9)+(4*1)+(3*4)+(2*6)+(1*0)=103
103 % 10 = 3
So 5914-60-3 is a valid CAS Registry Number.
