Check Digit Verification of cas no

The CAS Registry Mumber 4645-85-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,4 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4645-85:
(6*4)+(5*6)+(4*4)+(3*5)+(2*8)+(1*5)=106
106 % 10 = 6
So 4645-85-6 is a valid CAS Registry Number.
