The CAS Registry Mumber 3881-84-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,8 and 1 respectively; the second part has 2 digits, 8 and 4 respectively. Calculate Digit Verification of CAS Registry Number 3881-84: (6*3)+(5*8)+(4*8)+(3*1)+(2*8)+(1*4)=113 113 % 10 = 3 So 3881-84-3 is a valid CAS Registry Number.
