Check Digit Verification of cas no

The CAS Registry Mumber 4795-18-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,9 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4795-18:
(6*4)+(5*7)+(4*9)+(3*5)+(2*1)+(1*8)=120
120 % 10 = 0
So 4795-18-0 is a valid CAS Registry Number.
