Check Digit Verification of cas no

The CAS Registry Mumber 6843-39-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,4 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6843-39:
(6*6)+(5*8)+(4*4)+(3*3)+(2*3)+(1*9)=116
116 % 10 = 6
So 6843-39-6 is a valid CAS Registry Number.
