Check Digit Verification of cas no

The CAS Registry Mumber 289051-79-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,0,5 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 289051-79:
(8*2)+(7*8)+(6*9)+(5*0)+(4*5)+(3*1)+(2*7)+(1*9)=172
172 % 10 = 2
So 289051-79-2 is a valid CAS Registry Number.
