The CAS Registry Mumber 5100-27-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,0 and 0 respectively; the second part has 2 digits, 2 and 7 respectively. Calculate Digit Verification of CAS Registry Number 5100-27: (6*5)+(5*1)+(4*0)+(3*0)+(2*2)+(1*7)=46 46 % 10 = 6 So 5100-27-6 is a valid CAS Registry Number.
