Check Digit Verification of cas no

The CAS Registry Mumber 82297-69-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,9 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 82297-69:
(7*8)+(6*2)+(5*2)+(4*9)+(3*7)+(2*6)+(1*9)=156
156 % 10 = 6
So 82297-69-6 is a valid CAS Registry Number.
