139705-43-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139705-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,7,0 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139705-43:
(8*1)+(7*3)+(6*9)+(5*7)+(4*0)+(3*5)+(2*4)+(1*3)=144
144 % 10 = 4
So 139705-43-4 is a valid CAS Registry Number.
