Check Digit Verification of cas no

The CAS Registry Mumber 628-33-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 628-33:
(5*6)+(4*2)+(3*8)+(2*3)+(1*3)=71
71 % 10 = 1
So 628-33-1 is a valid CAS Registry Number.
