134039-43-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134039-43-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,0,3 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134039-43:
(8*1)+(7*3)+(6*4)+(5*0)+(4*3)+(3*9)+(2*4)+(1*3)=103
103 % 10 = 3
So 134039-43-3 is a valid CAS Registry Number.
