84325-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84325-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,3,2 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 84325-77:
(7*8)+(6*4)+(5*3)+(4*2)+(3*5)+(2*7)+(1*7)=139
139 % 10 = 9
So 84325-77-9 is a valid CAS Registry Number.
