The CAS Registry Mumber 67471-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,4,7 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 67471-20:
(7*6)+(6*7)+(5*4)+(4*7)+(3*1)+(2*2)+(1*0)=139
139 % 10 = 9
So 67471-20-9 is a valid CAS Registry Number.
