Check Digit Verification of cas no

The CAS Registry Mumber 4885-11-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,8 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4885-11:
(6*4)+(5*8)+(4*8)+(3*5)+(2*1)+(1*1)=114
114 % 10 = 4
So 4885-11-4 is a valid CAS Registry Number.
