Check Digit Verification of cas no

The CAS Registry Mumber 40968-90-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,6 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 40968-90:
(7*4)+(6*0)+(5*9)+(4*6)+(3*8)+(2*9)+(1*0)=139
139 % 10 = 9
So 40968-90-9 is a valid CAS Registry Number.
