Check Digit Verification of cas no

The CAS Registry Mumber 908254-34-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,8,2,5 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 908254-34:
(8*9)+(7*0)+(6*8)+(5*2)+(4*5)+(3*4)+(2*3)+(1*4)=172
172 % 10 = 2
So 908254-34-2 is a valid CAS Registry Number.
