Check Digit Verification of cas no

The CAS Registry Mumber 2305-53-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,0 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2305-53:
(6*2)+(5*3)+(4*0)+(3*5)+(2*5)+(1*3)=55
55 % 10 = 5
So 2305-53-5 is a valid CAS Registry Number.
