258335-89-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 258335-89-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,8,3,3 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 258335-89:
(8*2)+(7*5)+(6*8)+(5*3)+(4*3)+(3*5)+(2*8)+(1*9)=166
166 % 10 = 6
So 258335-89-6 is a valid CAS Registry Number.
