The CAS Registry Mumber 4744-02-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,4 and 4 respectively; the second part has 2 digits, 0 and 2 respectively. Calculate Digit Verification of CAS Registry Number 4744-02: (6*4)+(5*7)+(4*4)+(3*4)+(2*0)+(1*2)=89 89 % 10 = 9 So 4744-02-9 is a valid CAS Registry Number.
