Check Digit Verification of cas no

The CAS Registry Mumber 67640-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,6,4 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 67640-45:
(7*6)+(6*7)+(5*6)+(4*4)+(3*0)+(2*4)+(1*5)=143
143 % 10 = 3
So 67640-45-3 is a valid CAS Registry Number.
