The CAS Registry Mumber 21554-06-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,5,5 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21554-06:
(7*2)+(6*1)+(5*5)+(4*5)+(3*4)+(2*0)+(1*6)=83
83 % 10 = 3
So 21554-06-3 is a valid CAS Registry Number.
