Check Digit Verification of cas no

The CAS Registry Mumber 40634-99-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,3 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40634-99:
(7*4)+(6*0)+(5*6)+(4*3)+(3*4)+(2*9)+(1*9)=109
109 % 10 = 9
So 40634-99-9 is a valid CAS Registry Number.
