84690-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84690-90-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,6,9 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 84690-90:
(7*8)+(6*4)+(5*6)+(4*9)+(3*0)+(2*9)+(1*0)=164
164 % 10 = 4
So 84690-90-4 is a valid CAS Registry Number.
