The CAS Registry Mumber 39903-18-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,9,0 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 39903-18:
(7*3)+(6*9)+(5*9)+(4*0)+(3*3)+(2*1)+(1*8)=139
139 % 10 = 9
So 39903-18-9 is a valid CAS Registry Number.
