Check Digit Verification of cas no

The CAS Registry Mumber 84694-70-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,6,9 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 84694-70:
(7*8)+(6*4)+(5*6)+(4*9)+(3*4)+(2*7)+(1*0)=172
172 % 10 = 2
So 84694-70-2 is a valid CAS Registry Number.
