The CAS Registry Mumber 42866-54-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,8,6 and 6 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 42866-54: (7*4)+(6*2)+(5*8)+(4*6)+(3*6)+(2*5)+(1*4)=136 136 % 10 = 6 So 42866-54-6 is a valid CAS Registry Number.
