The CAS Registry Mumber 123751-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,5 and 1 respectively; the second part has 2 digits, 9 and 3 respectively. Calculate Digit Verification of CAS Registry Number 123751-93: (8*1)+(7*2)+(6*3)+(5*7)+(4*5)+(3*1)+(2*9)+(1*3)=119 119 % 10 = 9 So 123751-93-9 is a valid CAS Registry Number.
