Check Digit Verification of cas no

The CAS Registry Mumber 6227-05-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,2 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6227-05:
(6*6)+(5*2)+(4*2)+(3*7)+(2*0)+(1*5)=80
80 % 10 = 0
So 6227-05-0 is a valid CAS Registry Number.
