257290-41-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 257290-41-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,7,2,9 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 257290-41:
(8*2)+(7*5)+(6*7)+(5*2)+(4*9)+(3*0)+(2*4)+(1*1)=148
148 % 10 = 8
So 257290-41-8 is a valid CAS Registry Number.
