5508-42-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5508-42-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,0 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5508-42:
(6*5)+(5*5)+(4*0)+(3*8)+(2*4)+(1*2)=89
89 % 10 = 9
So 5508-42-9 is a valid CAS Registry Number.
