56889-84-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 56889-84-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,8,8 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 56889-84:
(7*5)+(6*6)+(5*8)+(4*8)+(3*9)+(2*8)+(1*4)=190
190 % 10 = 0
So 56889-84-0 is a valid CAS Registry Number.
