Check Digit Verification of cas no
The CAS Registry Mumber 40449-66-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,4,4 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40449-66:
(7*4)+(6*0)+(5*4)+(4*4)+(3*9)+(2*6)+(1*6)=109
109 % 10 = 9
So 40449-66-9 is a valid CAS Registry Number.
