Check Digit Verification of cas no

The CAS Registry Mumber 26805-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,8,0 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 26805-40:
(7*2)+(6*6)+(5*8)+(4*0)+(3*5)+(2*4)+(1*0)=113
113 % 10 = 3
So 26805-40-3 is a valid CAS Registry Number.
