131139-03-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131139-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,3 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 131139-03:
(8*1)+(7*3)+(6*1)+(5*1)+(4*3)+(3*9)+(2*0)+(1*3)=82
82 % 10 = 2
So 131139-03-2 is a valid CAS Registry Number.
