Check Digit Verification of cas no

The CAS Registry Mumber 5659-91-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,5 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5659-91:
(6*5)+(5*6)+(4*5)+(3*9)+(2*9)+(1*1)=126
126 % 10 = 6
So 5659-91-6 is a valid CAS Registry Number.
