The CAS Registry Mumber 2027-41-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,2 and 7 respectively; the second part has 2 digits, 4 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2027-41: (6*2)+(5*0)+(4*2)+(3*7)+(2*4)+(1*1)=50 50 % 10 = 0 So 2027-41-0 is a valid CAS Registry Number.
