Check Digit Verification of cas no

The CAS Registry Mumber 6227-21-0 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, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6227-21:
(6*6)+(5*2)+(4*2)+(3*7)+(2*2)+(1*1)=80
80 % 10 = 0
So 6227-21-0 is a valid CAS Registry Number.
