439858-03-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 439858-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,8,5 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 439858-03:
(8*4)+(7*3)+(6*9)+(5*8)+(4*5)+(3*8)+(2*0)+(1*3)=194
194 % 10 = 4
So 439858-03-4 is a valid CAS Registry Number.
