Check Digit Verification of cas no

The CAS Registry Mumber 16428-99-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,4,2 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 16428-99:
(7*1)+(6*6)+(5*4)+(4*2)+(3*8)+(2*9)+(1*9)=122
122 % 10 = 2
So 16428-99-2 is a valid CAS Registry Number.
