Check Digit Verification of cas no

The CAS Registry Mumber 890050-55-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,0,0,5 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 890050-55:
(8*8)+(7*9)+(6*0)+(5*0)+(4*5)+(3*0)+(2*5)+(1*5)=162
162 % 10 = 2
So 890050-55-2 is a valid CAS Registry Number.
