131502-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131502-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,0 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131502-53:
(8*1)+(7*3)+(6*1)+(5*5)+(4*0)+(3*2)+(2*5)+(1*3)=79
79 % 10 = 9
So 131502-53-9 is a valid CAS Registry Number.
