Check Digit Verification of cas no

The CAS Registry Mumber 4681-80-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,8 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4681-80:
(6*4)+(5*6)+(4*8)+(3*1)+(2*8)+(1*0)=105
105 % 10 = 5
So 4681-80-5 is a valid CAS Registry Number.
