84673-91-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84673-91-6 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 1 respectively.
Calculate Digit Verification of CAS Registry Number 84673-91:
(7*8)+(6*4)+(5*6)+(4*7)+(3*3)+(2*9)+(1*1)=166
166 % 10 = 6
So 84673-91-6 is a valid CAS Registry Number.
