Check Digit Verification of cas no

The CAS Registry Mumber 2543-06-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,4 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2543-06:
(6*2)+(5*5)+(4*4)+(3*3)+(2*0)+(1*6)=68
68 % 10 = 8
So 2543-06-8 is a valid CAS Registry Number.
