Check Digit Verification of cas no

The CAS Registry Mumber 2089-11-4 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, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2089-11:
(6*2)+(5*0)+(4*8)+(3*9)+(2*1)+(1*1)=74
74 % 10 = 4
So 2089-11-4 is a valid CAS Registry Number.
