Check Digit Verification of cas no

The CAS Registry Mumber 428-70-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 428-70:
(5*4)+(4*2)+(3*8)+(2*7)+(1*0)=66
66 % 10 = 6
So 428-70-6 is a valid CAS Registry Number.
