The CAS Registry Mumber 3919-38-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,1 and 9 respectively; the second part has 2 digits, 3 and 8 respectively. Calculate Digit Verification of CAS Registry Number 3919-38: (6*3)+(5*9)+(4*1)+(3*9)+(2*3)+(1*8)=108 108 % 10 = 8 So 3919-38-8 is a valid CAS Registry Number.
