Check Digit Verification of cas no

The CAS Registry Mumber 20491-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,9 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20491-40:
(7*2)+(6*0)+(5*4)+(4*9)+(3*1)+(2*4)+(1*0)=81
81 % 10 = 1
So 20491-40-1 is a valid CAS Registry Number.
