239803-55-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 239803-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,9,8,0 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 239803-55:
(8*2)+(7*3)+(6*9)+(5*8)+(4*0)+(3*3)+(2*5)+(1*5)=155
155 % 10 = 5
So 239803-55-5 is a valid CAS Registry Number.
