Check Digit Verification of cas no

The CAS Registry Mumber 81679-65-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,7 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81679-65:
(7*8)+(6*1)+(5*6)+(4*7)+(3*9)+(2*6)+(1*5)=164
164 % 10 = 4
So 81679-65-4 is a valid CAS Registry Number.
