Check Digit Verification of cas no

The CAS Registry Mumber 119256-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,2,5 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 119256-89:
(8*1)+(7*1)+(6*9)+(5*2)+(4*5)+(3*6)+(2*8)+(1*9)=142
142 % 10 = 2
So 119256-89-2 is a valid CAS Registry Number.
