5289-78-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5289-78-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,8 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.Calculate Digit Verification of CAS Registry Number 5289-78:
(6*5)+(5*2)+(4*8)+(3*9)+(2*7)+(1*8)=121
121 % 10 = 1
So 5289-78-1 is a valid CAS Registry Number.
