250-71-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 250-71-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,5 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 250-71:
(5*2)+(4*5)+(3*0)+(2*7)+(1*1)=45
45 % 10 = 5
So 250-71-5 is a valid CAS Registry Number.
