84369-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84369-90-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,3,6 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 84369-90:
(7*8)+(6*4)+(5*3)+(4*6)+(3*9)+(2*9)+(1*0)=164
164 % 10 = 4
So 84369-90-4 is a valid CAS Registry Number.
