The CAS Registry Mumber 6424-66-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.Calculate Digit Verification of CAS Registry Number 6424-66:
(6*6)+(5*4)+(4*2)+(3*4)+(2*6)+(1*6)=94
94 % 10 = 4
So 6424-66-4 is a valid CAS Registry Number.
