130443-13-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130443-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,4,4 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 130443-13:
(8*1)+(7*3)+(6*0)+(5*4)+(4*4)+(3*3)+(2*1)+(1*3)=79
79 % 10 = 9
So 130443-13-9 is a valid CAS Registry Number.
