473799-16-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 473799-16-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,3,7,9 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 473799-16:
(8*4)+(7*7)+(6*3)+(5*7)+(4*9)+(3*9)+(2*1)+(1*6)=205
205 % 10 = 5
So 473799-16-5 is a valid CAS Registry Number.
