153998-83-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 153998-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,9,9 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 153998-83:
(8*1)+(7*5)+(6*3)+(5*9)+(4*9)+(3*8)+(2*8)+(1*3)=185
185 % 10 = 5
So 153998-83-5 is a valid CAS Registry Number.
