84673-94-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84673-94-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,6,7 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 84673-94:
(7*8)+(6*4)+(5*6)+(4*7)+(3*3)+(2*9)+(1*4)=169
169 % 10 = 9
So 84673-94-9 is a valid CAS Registry Number.
