Check Digit Verification of cas no

The CAS Registry Mumber 39997-80-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,9,9 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 39997-80:
(7*3)+(6*9)+(5*9)+(4*9)+(3*7)+(2*8)+(1*0)=193
193 % 10 = 3
So 39997-80-3 is a valid CAS Registry Number.
