Check Digit Verification of cas no

The CAS Registry Mumber 4874-81-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,7 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4874-81:
(6*4)+(5*8)+(4*7)+(3*4)+(2*8)+(1*1)=121
121 % 10 = 1
So 4874-81-1 is a valid CAS Registry Number.
