The CAS Registry Mumber 1242-23-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,4 and 2 respectively; the second part has 2 digits, 2 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1242-23: (6*1)+(5*2)+(4*4)+(3*2)+(2*2)+(1*3)=45 45 % 10 = 5 So 1242-23-5 is a valid CAS Registry Number.
