257876-04-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 257876-04-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,7,8,7 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 257876-04:
(8*2)+(7*5)+(6*7)+(5*8)+(4*7)+(3*6)+(2*0)+(1*4)=183
183 % 10 = 3
So 257876-04-3 is a valid CAS Registry Number.
