255375-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 255375-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,5,3,7 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 255375-89:
(8*2)+(7*5)+(6*5)+(5*3)+(4*7)+(3*5)+(2*8)+(1*9)=164
164 % 10 = 4
So 255375-89-4 is a valid CAS Registry Number.
