131339-12-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131339-12-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,3 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 131339-12:
(8*1)+(7*3)+(6*1)+(5*3)+(4*3)+(3*9)+(2*1)+(1*2)=93
93 % 10 = 3
So 131339-12-3 is a valid CAS Registry Number.
