Check Digit Verification of cas no

The CAS Registry Mumber 4468-49-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,6 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4468-49:
(6*4)+(5*4)+(4*6)+(3*8)+(2*4)+(1*9)=109
109 % 10 = 9
So 4468-49-9 is a valid CAS Registry Number.
