131393-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131393-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,9 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131393-99:
(8*1)+(7*3)+(6*1)+(5*3)+(4*9)+(3*3)+(2*9)+(1*9)=122
122 % 10 = 2
So 131393-99-2 is a valid CAS Registry Number.
