The CAS Registry Mumber 3619-45-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,1 and 9 respectively; the second part has 2 digits, 4 and 5 respectively. Calculate Digit Verification of CAS Registry Number 3619-45: (6*3)+(5*6)+(4*1)+(3*9)+(2*4)+(1*5)=92 92 % 10 = 2 So 3619-45-2 is a valid CAS Registry Number.
