The CAS Registry Mumber 2801-74-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,0 and 1 respectively; the second part has 2 digits, 7 and 4 respectively. Calculate Digit Verification of CAS Registry Number 2801-74: (6*2)+(5*8)+(4*0)+(3*1)+(2*7)+(1*4)=73 73 % 10 = 3 So 2801-74-3 is a valid CAS Registry Number.
