Check Digit Verification of cas no

The CAS Registry Mumber 40917-51-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,1 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40917-51:
(7*4)+(6*0)+(5*9)+(4*1)+(3*7)+(2*5)+(1*1)=109
109 % 10 = 9
So 40917-51-9 is a valid CAS Registry Number.
