The CAS Registry Mumber 4497-08-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,9 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4497-08:
(6*4)+(5*4)+(4*9)+(3*7)+(2*0)+(1*8)=109
109 % 10 = 9
So 4497-08-9 is a valid CAS Registry Number.
