84161-19-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84161-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,1,6 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 84161-19:
(7*8)+(6*4)+(5*1)+(4*6)+(3*1)+(2*1)+(1*9)=123
123 % 10 = 3
So 84161-19-3 is a valid CAS Registry Number.
