The CAS Registry Mumber 2845-72-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,4 and 5 respectively; the second part has 2 digits, 7 and 2 respectively. Calculate Digit Verification of CAS Registry Number 2845-72: (6*2)+(5*8)+(4*4)+(3*5)+(2*7)+(1*2)=99 99 % 10 = 9 So 2845-72-9 is a valid CAS Registry Number.
