Check Digit Verification of cas no

The CAS Registry Mumber 78600-80-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,6,0 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78600-80:
(7*7)+(6*8)+(5*6)+(4*0)+(3*0)+(2*8)+(1*0)=143
143 % 10 = 3
So 78600-80-3 is a valid CAS Registry Number.
