857489-47-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 857489-47-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,4,8 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 857489-47:
(8*8)+(7*5)+(6*7)+(5*4)+(4*8)+(3*9)+(2*4)+(1*7)=235
235 % 10 = 5
So 857489-47-5 is a valid CAS Registry Number.
