Check Digit Verification of cas no
The CAS Registry Mumber 43028-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,3,0,2 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 43028-69:
(7*4)+(6*3)+(5*0)+(4*2)+(3*8)+(2*6)+(1*9)=99
99 % 10 = 9
So 43028-69-9 is a valid CAS Registry Number.
