1257441-90-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1257441-90-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,4,4 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1257441-90:
(9*1)+(8*2)+(7*5)+(6*7)+(5*4)+(4*4)+(3*1)+(2*9)+(1*0)=159
159 % 10 = 9
So 1257441-90-9 is a valid CAS Registry Number.
