Check Digit Verification of cas no

The CAS Registry Mumber 5653-91-8 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 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5653-91:
(6*5)+(5*6)+(4*5)+(3*3)+(2*9)+(1*1)=108
108 % 10 = 8
So 5653-91-8 is a valid CAS Registry Number.
