The CAS Registry Mumber 28540-46-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,5,4 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 28540-46:
(7*2)+(6*8)+(5*5)+(4*4)+(3*0)+(2*4)+(1*6)=117
117 % 10 = 7
So 28540-46-7 is a valid CAS Registry Number.
