Check Digit Verification of cas no

The CAS Registry Mumber 209069-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,0,6 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 209069-53:
(8*2)+(7*0)+(6*9)+(5*0)+(4*6)+(3*9)+(2*5)+(1*3)=134
134 % 10 = 4
So 209069-53-4 is a valid CAS Registry Number.
