Check Digit Verification of cas no

The CAS Registry Mumber 4279-85-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,7 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4279-85:
(6*4)+(5*2)+(4*7)+(3*9)+(2*8)+(1*5)=110
110 % 10 = 0
So 4279-85-0 is a valid CAS Registry Number.
