Check Digit Verification of cas no

The CAS Registry Mumber 2297-02-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,9 and 7 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2297-02:
(6*2)+(5*2)+(4*9)+(3*7)+(2*0)+(1*2)=81
81 % 10 = 1
So 2297-02-1 is a valid CAS Registry Number.
