Check Digit Verification of cas no

The CAS Registry Mumber 6470-58-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,7 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6470-58:
(6*6)+(5*4)+(4*7)+(3*0)+(2*5)+(1*8)=102
102 % 10 = 2
So 6470-58-2 is a valid CAS Registry Number.
