Check Digit Verification of cas no

The CAS Registry Mumber 934-19-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 934-19:
(5*9)+(4*3)+(3*4)+(2*1)+(1*9)=80
80 % 10 = 0
So 934-19-0 is a valid CAS Registry Number.
