245039-83-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 245039-83-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,5,0,3 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 245039-83:
(8*2)+(7*4)+(6*5)+(5*0)+(4*3)+(3*9)+(2*8)+(1*3)=132
132 % 10 = 2
So 245039-83-2 is a valid CAS Registry Number.
