The CAS Registry Mumber 2475-10-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,7 and 5 respectively; the second part has 2 digits, 1 and 0 respectively. Calculate Digit Verification of CAS Registry Number 2475-10: (6*2)+(5*4)+(4*7)+(3*5)+(2*1)+(1*0)=77 77 % 10 = 7 So 2475-10-7 is a valid CAS Registry Number.
