Check Digit Verification of cas no

The CAS Registry Mumber 142285-73-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,2,8 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142285-73:
(8*1)+(7*4)+(6*2)+(5*2)+(4*8)+(3*5)+(2*7)+(1*3)=122
122 % 10 = 2
So 142285-73-2 is a valid CAS Registry Number.
