54808-56-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54808-56-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,8,0 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 54808-56:
(7*5)+(6*4)+(5*8)+(4*0)+(3*8)+(2*5)+(1*6)=139
139 % 10 = 9
So 54808-56-9 is a valid CAS Registry Number.
