258531-71-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 258531-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,8,5,3 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 258531-71:
(8*2)+(7*5)+(6*8)+(5*5)+(4*3)+(3*1)+(2*7)+(1*1)=154
154 % 10 = 4
So 258531-71-4 is a valid CAS Registry Number.
