257947-31-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 257947-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,7,9,4 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 257947-31:
(8*2)+(7*5)+(6*7)+(5*9)+(4*4)+(3*7)+(2*3)+(1*1)=182
182 % 10 = 2
So 257947-31-2 is a valid CAS Registry Number.
