The CAS Registry Mumber 1651-24-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 1 respectively; the second part has 2 digits, 2 and 4 respectively. Calculate Digit Verification of CAS Registry Number 1651-24: (6*1)+(5*6)+(4*5)+(3*1)+(2*2)+(1*4)=67 67 % 10 = 7 So 1651-24-7 is a valid CAS Registry Number.
