The CAS Registry Mumber 845-89-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,4 and 5 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 845-89: (5*8)+(4*4)+(3*5)+(2*8)+(1*9)=96 96 % 10 = 6 So 845-89-6 is a valid CAS Registry Number.
