Check Digit Verification of cas no

The CAS Registry Mumber 2109-97-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,0 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2109-97:
(6*2)+(5*1)+(4*0)+(3*9)+(2*9)+(1*7)=69
69 % 10 = 9
So 2109-97-9 is a valid CAS Registry Number.
