554408-71-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 554408-71-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,4,4,0 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 554408-71:
(8*5)+(7*5)+(6*4)+(5*4)+(4*0)+(3*8)+(2*7)+(1*1)=158
158 % 10 = 8
So 554408-71-8 is a valid CAS Registry Number.
