Check Digit Verification of cas no

The CAS Registry Mumber 289891-56-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,8,9 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 289891-56:
(8*2)+(7*8)+(6*9)+(5*8)+(4*9)+(3*1)+(2*5)+(1*6)=221
221 % 10 = 1
So 289891-56-1 is a valid CAS Registry Number.
