The CAS Registry Mumber 2107-46-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,0 and 7 respectively; the second part has 2 digits, 4 and 6 respectively. Calculate Digit Verification of CAS Registry Number 2107-46: (6*2)+(5*1)+(4*0)+(3*7)+(2*4)+(1*6)=52 52 % 10 = 2 So 2107-46-2 is a valid CAS Registry Number.
