The CAS Registry Mumber 2204-81-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,0 and 4 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2204-81: (6*2)+(5*2)+(4*0)+(3*4)+(2*8)+(1*1)=51 51 % 10 = 1 So 2204-81-1 is a valid CAS Registry Number.
