The CAS Registry Mumber 3619-38-3 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, 3 and 8 respectively. Calculate Digit Verification of CAS Registry Number 3619-38: (6*3)+(5*6)+(4*1)+(3*9)+(2*3)+(1*8)=93 93 % 10 = 3 So 3619-38-3 is a valid CAS Registry Number.
