84161-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84161-23-9 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, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 84161-23:
(7*8)+(6*4)+(5*1)+(4*6)+(3*1)+(2*2)+(1*3)=119
119 % 10 = 9
So 84161-23-9 is a valid CAS Registry Number.
