The CAS Registry Mumber 38254-52-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,2,5 and 4 respectively; the second part has 2 digits, 5 and 2 respectively. Calculate Digit Verification of CAS Registry Number 38254-52: (7*3)+(6*8)+(5*2)+(4*5)+(3*4)+(2*5)+(1*2)=123 123 % 10 = 3 So 38254-52-3 is a valid CAS Registry Number.
