Check Digit Verification of cas no

The CAS Registry Mumber 1116-50-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,1 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1116-50:
(6*1)+(5*1)+(4*1)+(3*6)+(2*5)+(1*0)=43
43 % 10 = 3
So 1116-50-3 is a valid CAS Registry Number.
