258270-23-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 258270-23-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,8,2,7 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 258270-23:
(8*2)+(7*5)+(6*8)+(5*2)+(4*7)+(3*0)+(2*2)+(1*3)=144
144 % 10 = 4
So 258270-23-4 is a valid CAS Registry Number.
