439808-08-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 439808-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,8,0 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 439808-08:
(8*4)+(7*3)+(6*9)+(5*8)+(4*0)+(3*8)+(2*0)+(1*8)=179
179 % 10 = 9
So 439808-08-9 is a valid CAS Registry Number.
