Check Digit Verification of cas no

The CAS Registry Mumber 2893-91-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,9 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2893-91:
(6*2)+(5*8)+(4*9)+(3*3)+(2*9)+(1*1)=116
116 % 10 = 6
So 2893-91-6 is a valid CAS Registry Number.
