251940-05-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 251940-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,9,4 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 251940-05:
(8*2)+(7*5)+(6*1)+(5*9)+(4*4)+(3*0)+(2*0)+(1*5)=123
123 % 10 = 3
So 251940-05-3 is a valid CAS Registry Number.
