The CAS Registry Mumber 1576-22-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,7 and 6 respectively; the second part has 2 digits, 2 and 2 respectively. Calculate Digit Verification of CAS Registry Number 1576-22: (6*1)+(5*5)+(4*7)+(3*6)+(2*2)+(1*2)=83 83 % 10 = 3 So 1576-22-3 is a valid CAS Registry Number.
