Check Digit Verification of cas no

The CAS Registry Mumber 20566-35-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,6 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20566-35:
(7*2)+(6*0)+(5*5)+(4*6)+(3*6)+(2*3)+(1*5)=92
92 % 10 = 2
So 20566-35-2 is a valid CAS Registry Number.
