The CAS Registry Mumber 29654-54-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,6,5 and 4 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 29654-54: (7*2)+(6*9)+(5*6)+(4*5)+(3*4)+(2*5)+(1*4)=144 144 % 10 = 4 So 29654-54-4 is a valid CAS Registry Number.
