54903-18-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54903-18-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,9,0 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 54903-18:
(7*5)+(6*4)+(5*9)+(4*0)+(3*3)+(2*1)+(1*8)=123
123 % 10 = 3
So 54903-18-3 is a valid CAS Registry Number.
