257929-19-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 257929-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,7,9,2 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 257929-19:
(8*2)+(7*5)+(6*7)+(5*9)+(4*2)+(3*9)+(2*1)+(1*9)=184
184 % 10 = 4
So 257929-19-4 is a valid CAS Registry Number.
