1257232-39-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1257232-39-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,2,3 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1257232-39:
(9*1)+(8*2)+(7*5)+(6*7)+(5*2)+(4*3)+(3*2)+(2*3)+(1*9)=145
145 % 10 = 5
So 1257232-39-5 is a valid CAS Registry Number.
