Check Digit Verification of cas no

The CAS Registry Mumber 2089-75-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,8 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2089-75:
(6*2)+(5*0)+(4*8)+(3*9)+(2*7)+(1*5)=90
90 % 10 = 0
So 2089-75-0 is a valid CAS Registry Number.
